doi: 10.1038/nmeth.3319, Torre, E. R., and Steward, O. If someday your work gets published, show it off here! Data represent the average value of 10 sampled cells per condition plotted as individual data points, and the mean and median of 6 independent experiments (n = 6). Today we're going to talk about Image Js use in immunohistochemistry. An alternative approach that is closer to absolute quantitation of binding sites for individual mAbs is use of the so-called "antigen-binding capacity" (or ABC) beads. The number of objects (translation sites) are scored in each interval (bin) with the Analyze Particles function (default settings; Figure 1; workflow B; step 9). *p < 0.05; two-tailed t-test. Scale bar, 10 m. Did you know? To calculate the total fluorescent intensity in the soma, in neurites or in other desired interval disregarding the bin position, values retrieved from each bin of interest were summed up (Figure 1; workflow A; step 5i). Pairing the cholinergic agonist carbachol with patterned Schaffer collateral stimulation initiates protein synthesis in hippocampal CA1 pyramidal cell dendrites via a muscarinic, NMDA-dependent mechanism. you should identify those pixels Markers used as counterstain for neurite selection were adjusted for an optimal visualization in figures. WebClick the More>> button in the ROI manager and select the Multi Measure button to Adjust the detector settings: Depending on the desired range of fluorescence intensity readings, adjust the flow cytometers voltage and power settings to optimize the dynamic range of your flow cytometer. Box and whisker graph representing the total fluorescent intensity of the calreticulin staining along the first 20 m of calreticulin- and puromycin-positive somata. (2017). Calculate the mean fluorescence intensity value for each sample or condition. Additionally, our results unravel a previously unreported effect of A oligomers on discrete translation events in neurites (Figures 3E,I). We first performed edge detection to find discontinuities in our puromycin labeling that could result from a punctate staining arising from discrete positive foci. Binarized images used for assisted quantification of translation sites were obtained as will be specified below. For better light coupling in miniaturized systems, efforts have been made to incorporate both the source and detector on the chip itself. (2018). (G) Discrete puromycin puncta scored by observer 1 in DMSO- and A-treated neurons in 15 bins covering a distance of 150 m from the edge of the soma (Tau+ neurite) and in (H) distal sites of Tau-positive neurites disregarding the bin position [Tau+ (distal)]. Proteins involved in mitochondrial function such as LaminB2 (Yoon et al., 2012) or COXIV (Aschrafi et al., 2010) are locally synthesized in axons and contribute to their maintenance in post-developmental stages. rectangle, circle, polygon or freeform) From the Analyze menu select set measurements. Measuring mean fluorescence intensity using ImageJ is relatively simple. and how do I use the DAPI nuclei stains to "normalize" the MFI data like my mentor said - does it have anything to do with counting the number of nuclei/DAPI stains and relating it to the MFI value from the red signal? It doesn't appear in any feeds, and anyone with a direct link to it will see a message like this one. The fitting curves for Cybesin in the cancer tissue (thick solid line) and Cybesin in the normal tissue (thin solid line) were calculated using Eq.12.18 in the text and the corresponding data are shown by the dashed and dot-dashed lines in (b). It was classically thought that proteins that support dendritic and axonal functions are synthesized in the soma and then transported to their target destination at peripheral sites of the neuron. Bldg C17, Optics Valley International Biomedicine Park, Wuhan, China. These results are compatible with other experiments performed in our laboratory aimed at labeling neuritic RNAs with alternative techniques (data not shown). (H) Calreticulin intensity was measured in DMSO- and A-treated neurons in 15 bins covering a distance of 150 m from the cell nucleus. There are a whole bunch of different ways to do it, but in your case it will be most sensible to look at pixel intensity. In situ visualization and dynamics of newly synthesized proteins in rat hippocampal neurons. Discrete puromycin puncta were visually scored in each bin covering a distance of 150 m from the center of the cell nucleus or from the edge of the soma (Figure 1; workflow A; step 4ii). Images give everyone a chance to understand the problem. Maceral (V, vitrinite; E, exinite; and I, inertinite) and mineral matter (M) bands and particles in a bituminous coal. Negative controls showed significantly less amount of foci in neurites regardless of whether quantification was performed manually in non-binarized images (Figure 3F; left graph) or with the particle analyzer in filtered and binarized images (Figure 3F; right graph). Dendritic morphology of CA1 pyramidal neurones from the rat hippocampus: II. Select the Mean Gray Value option from the Measure menu. Press J to jump to the feed. The results can then be used to measure the intensity of staining, as well as its degree of homogeneity. 14, 437446. In addition, the dye is more concentrated in cancerous tissue due to higher adsorption of Cybesin (Cytate), as shown by the larger emission intensity in Fig.12.7(a). J. Biol. Finally, regardless of the effect of A142, puromycin intensity was significantly reduced in neurites when cells were co-incubated with the translation inhibitor anisomycin (+ anis + puro, Figure 2A; 5 and 6, Figures 2AC). 2, 284291. (C) Following workflow B, selected neurites were straighten, smoothen and binarized with the MaxEntropy mask (smooth > binary > MaxEntropy). OLEDs also have flexibility in terms of fabrication and can be made in any desired size and shape by photolithographic techniques [6]. Similarly, despite detecting a significant accumulation of discrete puromycin foci in both control and A-treated cells after 30 min of puromycin exposure compared to shorter pulses, these were significantly higher when A oligomers were added to the cultures (Figure 4F). Step 1: Import Image: Open Image J, FileOpen: Open the Image to be MB-U is a predoctoral fellow funded by the University of the Basque Country (UPV/EHU). Cell Neurosci. Graphs show values scored in raw (manual) images by observer 1 and observer 2 in DMSO- (blue) and A-treated neurons (red) cultured in 6 independent experiments (n = 6). The fitting results also show rcancer>rnormal for both Cybesin and Cytate. Banker, G., and Goslin, K. (1998). For convenience, all the experimental and calculated parameters for the two receptor-targeted contrast agents (Cybesin and Cytate) in prostate tissues are listed in Table12.2. Cells were washed with cold PBS with 3 g.ml1 digitonin (Sigma Aldrich) and fixed in 4% paraformaldehyde (PFA), 4% sucrose in PBS. Data represent the average value of 10 sampled cells per condition shown as individual data points, and the mean and median of 6 independent experiments (n = 6). doi: 10.1038/nn.2583, Quintela-Lopez, T., Ortiz-Sanz, C., Serrano-Regal, M. P., Gaminde-Blasco, A., Valero, J., Baleriola, J., et al. Cells were washed twice with Hanks balanced salt solution (HBSS, Gibco) and resuspended in plating medium containing 10% fetal bovine serum, 2 mM L-glutamine and 50 U.ml1 penicillin-streptomycin in Neurobasal (all from Gibco). However, when focusing on distal sites of the neurites (> 30 m from the soma) disregarding the bin position, none of them detected changes between controls and A treatments (Figures 4H,J), in line with previous results (Figure 3I). Samples processed for puromycin detection in Tau-positive neurites were incubated for 20 min with 500 nM SYTO RNASelect, a fluorescent dye that selectively binds RNA (Savas et al., 2010). By incubating beads with the fluorochrome-conjugated antibody of choice, the median channel fluorescence value associated with a specific number of molecules of bound mAb can be determined using a plot similar to the one shown above (Fig. J. Comp. For later time points the apoptotic cells take over and the peak is propagated back to lower fluorescence intensities due to the altered replication of NP. These results are compatible with changes in local translation but they do not address whether actual local sites of protein synthesis are affected by A oligomers. (1992). The use of a two-dimensional (2D) PDMS lens in a microfluidic device with channels for both liquid flow and insertion of optical fibers for fluorescence excitation (Fig. In contrast to the normal inorganic LEDs, organic light-emitting diodes (OLEDs) have flat surfaces, thus making integration easier with microfluidic devices. Samples were washed three times with PBS and mounted with ProLong Gold antifade reagent (P-36930, Invitrogen). A huge variety of latex beads are available commercially, but for fluorescent semiquantitation purposes, a kit containing a minimum of five populations of beads with increasing fluorescence intensities should be used. Scale bar, 10 m in heatmaps. A transient bimodality forms which becomes well-defined after 18 h. As soon as there are less and less uninfected cells the bimodality vanishes (22 h) and only infected and more and more apoptotic cells contribute to the overall cell distribution. Demonstration of local protein synthesis within dendrites using a new cell culture system that permits the isolation of living axons and dendrites from their cell bodies. We have observed that A increases the synthesis of neuritic proteins as well as the fraction of translating RNAs in distal sites of the neurite, suggesting an induction of local protein synthesis. Select the Analyze menu option, then select the Measure menu option. Fluorescence intensity is an important parameter that can be used to measure the concentration of a target in a fluorescence detection method. In dynamic or collisional quenching, interaction of an excited state fluorophore with the quencher results in radiationless deactivation of the fluorophore to the ground state. AD is characterized by synaptic dysfunction during early stages (Palop and Mucke, 2010). 1, 2, and 3, DMSO-treated cells exposed to puromycin for 5, 10, and 30 mins respectively; 4, 5, and 6, A-treated cells exposed to puromycin for 5, 10, and 30 mins, respectively. (L) Spearman correlation between non-assisted [wA (DMSO, A)] or assisted quantification [wB (DMSO, A)] of translation sites (# puromycin foci) and protein production (mean puro intensity). Notice that rounded up mitotic cells appear to have a much higher level of staining due to its smaller size concentrating the staining in a smaller space. The light output side was essentially a mirror image of this process. Divide each mean fluorescence intensity value by the SD to obtain the standardized value. doi: 10.1002/cne.903600112. doi: 10.1002/cne.903600111, Bannister, N. J., and Larkman, A. U. Images show the same cells used as examples for the workflow in Figure 1. doi: 10.15252/embr.201745435, Wong, H. H., Lin, J. Q., Strohl, F., Roque, C. G., Cioni, J. M., Cagnetta, R., et al. Furthermore, since the excitation wavelength of 800nm used for pumping is close to the strong absorption peak of Cybesin (Cytate) tissue (Pu et al., 2007; Pu et al., 2008; Pu et al., 2005), the stained cancerous tissues will absorb more photons than the stained normal tissue; thus the Cybesin (Cytate) contained in the deep layer of the stained cancerous tissue will have less opportunity to be excited by the laser than that in the normal tissue. Local translation of RhoA regulates growth cone collapse. In the correlation graphs, linear regression of the data was performed to evaluate the differences between slopes (ANCOVA). Some variations of the aforementioned techniques such as Puro-PLA or FUNCAT-PLA have been used to accurately measure discrete translation sites of specific proteins along neurites (Tom Dieck et al., 2015). Be thorough in outlining the question(s) that you are trying to answer. Other modifications of SUnSET have been recently used to evaluate overall discrete intra-neuritic and intra-dendritic translation events. Figure 4. Have these images been acquired with a colorcamera? Above, this is the share of immunohistochemical analysis using Image J. The image is finally divided in 15 concentric circles at 10 m intervals emerging from the edge of the soma with the concentric_circles plugin. The default normalized kernel is sufficient to enhance structures in the periphery of the neurons smaller than 5 5 pixels and it is thus suitable to highlight puromycin-positive translation sites distal to the center of the cell nucleus (Figure 1; workflow B; step 1). With images, we are dealing with varying pixel intensity across space. So you need to split channels into RGB and work with the Red channel. Thus, the combination of RNA and protein staining techniques followed by image processing and binarization, and object-based colocalization can be successfully used to detect sites of local RNA translation in neurons. However, in the 19th century, the possibility of neurites, especially axons, producing their own proteins locally was already hypothesized (review in Bolton, 1901). Additional details for generation of correction factors can be found in Lakowicz (2006). 14:547. doi: 10.3389/fnins.2020.00547. As a complementary analysis method we developed 'NucTracer', which uses DAPI stained nucleoids as a proxy for single cells. To calculate the total fluorescent intensity in the soma, in neurites or in other desired interval disregarding the bin position, values retrieved from each bin of interest were summed up ( Figure 1; workflow A; step 5i). The results can then be used to measure the area of immunopositivity and/or the intensity of the staining. The fluorescence intensity for detection of fluorescein isothiocyanate (FITC)-tagged albumin molecules almost doubled in the case of PDMS lenses as compared to a flat airPDMS interface. The longer decay time of free Cybesin (Cytate) molecules in cancerous prostate tissue indicates the higher local viscosity of cancerous prostate tissue. The bin ranging from 0 to 10 m (first bin within the soma) was discarded as no discrete puncta could be visualized (N/A in Figures 3D,E). We quantified discrete puromycin-positive foci in distal neuritic sites in response to A142 with the particle analyzer after image processing with the convolver (assisted quantification). Light-emitting diodes (LEDs) in general are 3D structures which make integration in a microdevice difficult. Scale bar, 50 m. Rev. Coal macerals have different colors and fluorescence intensities and can be identified under the microscope. The number of RNA granules was scored in 15 bins covering a distance of 150 m from the edge of the soma and no significant differences were observed between experimental conditions, regardless of whether neurons were fed with puromycin for 5, 10, or 30 min (Figure 5B). Box and whisker graph representing the total fluorescent intensity of the calreticulin staining along 130 m of calreticulin- and puromycin-positive neurites. Green organic light-emitting diode (OLED) acts as the light source, the polydimethylsiloxane (PDMS) microfluidic chip contains the dye detection volume, and polarizer 2 is used to filter out the excitation light and allows only the emission signal to pass through to the organic photodiode (OPD). Images were acquired using an objective EC Plan-Neofluar 40/1,30 Oil DIC M27 on an Axio-Observer Z1 microscope equipped with AxioCam MRm Rev. Thus local translation events can be easily overlooked under the microscope. To quantify the puromycin fluorescent intensity as a measure of protein production (Figure 1; workflow A), the longest puromycin- and III tubulin-positive neurite or puromycin- and Tau-positive neurite from randomly selected cells was straightened with the Segmented Line tool in FIJI/ImageJ: Figure 1. I picked "Triangle" for the image you uploaded. Alternatively, you can go to Analyze Set Measurements and check off the box next to Limit to Threshold. Then use Image Adjust Threshold to highlight the area you want to analyze, and then Analyze Measure will give you intensity measurements in just your thresholded area. You also have the issue that with this method the signal that you are using to delineate "what is a cell" is also the signal you are measuring. Synthetic mechanisms in the axon. Counterstain with the anti-Tau antibody is shown (red). In particular, after a nerve injury, mRNAs are locally translated and newly synthesized proteins contribute to axonal regeneration (Terenzio et al., 2018). The main source of fluctuation comes from the molecules diffusing in and out of the examined volume. The fitting results show that (I0cancer/I0normal) for Cytate-stained cancerous tissue and normal tissues is ~3.470.57, indicating that Cytate is preferentially taken up by cancerous prostate tissue (Pu et al., 2007; Pu et al., 2008; Pu et al., 2005). Discrete puromycin puncta were measured (analyze particles) in neurons in 15 bins covering a distance of 150 m from the cell nucleus or from the edge of the soma using the concentric_circles plugin (step 8). Mononuclear cells were incubated overnight in the presence or absence of a tumor cell lysate and labeled with anti-CD3, anti-CD69, anti-CD16, and anti-CD56. (Fig. I would recommend that you download FIJI (if you haven't already) here: https://fiji.sc/. It has a lot of pre-downloaded scientific addons and plug Cell Death Dis. Cells were then processed for Calreticulin (Calr) and puromycin immunostaining. Single molecule detection has also been reached. doi: 10.1523/JNEUROSCI.02-03-00284.1982, Terenzio, M., Koley, S., Samra, N., Rishal, I., Zhao, Q., Sahoo, P. K., et al. Coble, in Subsea Optics and Imaging, 2013. A role for huntington disease protein in dendritic RNA granules. The line is the best linear fit to the average lifetime obtained by the frequency domain method (Table 2). Prepare the specimen chamber: Place your sample in the flow cytometers specimen chamber and circulate it for at least 5 minutes to ensure that the sample is evenly distributed within the chamber. ****p < 0.0001; significant differences between slopes. (3) Or we just measure the whole thing, which can be done by using the threshold function. Most Effective Erectile Dysfunction Treatments. The antibiotic puromycin is an aminoacyl-tRNA analog that incorporates into the polypeptide chains during translation elongation, leading to translation termination (Yarmolinsky and Haba, 1959). Taking a single median value from a fluorescence signal that contains multiple log-normal distributions should be avoided (e.g., the PI signal in Figure 3A, which shows at least three subpopulations). U.S.A. 110, 1620516210. Holbrook et al. Here we describe a strategy to enhance puromycin hotspots in neurites following SUnSET, based solely on image processing and the assisted quantification of the resulting objects. doi: 10.15252/embj.201797724, Palop, J. J., and Mucke, L. (2010). thank you so much for the help!just to clarify, is the MFI represented by the "mean" section of the results table (instead of area, or integrated density or anything else)? In order to synthesize proteins locally, messenger RNAs (mRNAs) and components of translational machinery must be transported to neurites. Image color quantification (manual): This method involves visually assessing the intensity of the immunofluorescent staining in the predetermined regions of interest and assigning a numerical score to it. Our technique does not require the incubation of the cells with any translation inhibitor besides puromycin, and it avoids the processing of the samples for proximity ligation assay, which can be pricy and time consuming. The RER is enriched in proteins involved in the folding of nascent polypeptides, being the Calnexin/Calreticulin system one the best known protein complexes (Rutkevich and Williams, 2011). Additionally, puromycin hotspots were readily visible in distal sites of the neurites, especially in A-treated cells (4, intensity profile and heatmap in Figure 2B). The high sensitivity of the detectors even allows the measurement of the fluorescence fluctuations of a single molecule. Then there is the analysis of the individual in the picture , Step 6: Organize the data, EditCopy, you can Copy the data to Excel. Intra-axonal synthesis of -actin (Leung et al., 2006), RhoA (Wu et al., 2005), or Par3 (Hengst et al., 2009) is important in growth cone behavior and axon elongation during nervous system development. Figure 5.2. Conversely, a significant moderate positive correlation was observed between parameters when translation sites were counted in binarized images with the particle analyzer (wB, Figure 4L). Sprague-Dawley rats were bred in local facilities and embryonic brains were obtained from CO2 euthanized pregnant rats. AB received funding from the Portuguese Foundation for Science and Technology (FCT) in the context of the FCT funded University of Minho M.D./Ph.D. The examples discussed earlier have the light source and detector placed outside the microchip. EMBO Rep. 18, 693711. Collect data: Run the flow cytometer to collect data on the fluorescence intensity of your sample. (2006) provide some excellent examples of EEMs collected with and without the various options of reference detector and spectral corrections. (2018). Figure 2.2 shows the relation between reflectance and the carbon contents of coals. Translation foci were scored with the particle analyzer in 15 bins covering a distance of 150 m from the edge of the cell body. Natl. Different configurations in terms of placement of the light source and detector have been implemented in fluorescence-based microchips. However, we did observe an accumulation of co-localized foci in A-treated cells that was not detected in controls when neurons were exposed to puromycin for 30 min compared to the 5-min treatment (Figure 5D). This will show a graph charting the mean intensity against the sample population. The first utilizes modified amino acids, such azidohomoalanine, that get incorporated into the nascent polypeptide chain. Newly synthesized proteins are tagged with puromycin and endogenous RNAs labeled with SYTO. Neurosci. Interestingly, A142 increased the proportion of RNA translation in distal sites of Tau-positive neurites, beyond the ER domain. Dieterich, D. C., Hodas, J. J., Gouzer, G., Shadrin, I. Y., Ngo, J. T., Triller, A., et al. doi: 10.1038/nn1775, Li, C., and Gotz, J. We applied the processing protocol followed for puromycin staining to SYTO-positive neurites. Create an account to follow your favorite communities and start taking part in conversations. (A) Rat hippocampal neurons were grown for 9 DIV and were treated with DMSO or A142 oligomers for 24 h. Cells were incubated with puromycin for 30 mins and processed for III tubulin (gray) and puromycin immunostaining (heatmaps). Images were converted to 8-bit and binarized with the MaxEntropy mask. MG is a predoctoral fellow funded by the Basque Government. Mean is a kind of average. We provide you with the favorite products of protein and immune research users, from basic immunological products, such as protein extraction and quantification, to internal reference label antibodies, primary antibodies and secondary antibodies for immunological experiments; the favorite products of cell research users, from Dyes and kits for detecting cell status, organelle extraction kits, cell substructure staining and tracking and cell metabolism detection products, to cytokine and protein detection kits for cell culture, just to help your research career ! (2010). By considering that the fluorescence intensity fluctuates around a mean value: the autocorrelation function can be written as: FCS have been extensively used to extract diffusion coefficient of small fluorescent latex bead in solution, showing the influence of the bead radius or solvent properties. Select the Split Channels option from the ImageJ menu. 1 and 2: no puromycin incubation in DMSO- and A-treated neurons, respectively. In fluorescence correlation spectroscopy (FCS), one measures the fluorescence intensity of a very small sample volume (1015), for example, under a confocal microscope, and records its fluctuations in time, F(t), around an equilibrium value, F. Here we describe an object-based analysis used to visualize and quantify local RNA translation sites in neurites. For analyzing fluorescence images, there are some really good guides online, such as these: https://theolb.readthedocs.io/en/latest/imaging/measuring-cell-fluorescence-using-imagej.html, https://www.unige.ch/medecine/bioimaging/files/1914/1208/6000/Quantification.pdf, https://confocal.uconn.edu/wp-content/uploads/sites/1081/2016/02/2014-05_Analyzing_fluorescence_microscopy_images.pdf, https://kpif.umbc.edu/image-processing-resources/imagej-fiji/determining-fluorescence-intensity-and-positive-signal/. (b) Time-dependent fluorescence anisotropy calculated using Eq.12.7 in the text and the measured data shown in Fig.12.5(a,b). Figure 2. Flow cytometry: This method involves using immunofluorescent staining to quantify the number of cells in a certain population. SYTO RNASelect green fluorescent dye selectively binds neuritic RNA (Figure 5A). doi: 10.1523/JNEUROSCI.13-03-01010.1993, Giuditta, A., Dettbarn, W. D., and Brzin, M. (1968). Dynamic quenching of R6G: Lifetime of rhodamine 6G decreases with increasing iodide ion concentration. Thus, dysregulation of the local translatome in neurons might play a more relevant role in AD than previously acknowledged. Amyloid-beta-induced neuronal dysfunction in Alzheimers disease: from synapses toward neural networks. This statement has at least two caveats, however. ****p < 0.0001 (interaction); two-way ANOVA. The lifetimes were measured using a frequency domain setup. All animal protocols followed the European directive 2010/63/EU and were approved by the UPV/EHU ethics committee. and how do I use the DAPI nuclei stains to "normalize" the MFI data like my mentor said - does it have anything to do with counting the number of nuclei/DAPI stains and relating it to the MFI value from the red signal? Science 364:6441. doi: 10.1126/science.aau3644, Hengst, U., Deglincerti, A., Kim, H. J., Jeon, N. L., and Jaffrey, S. R. (2009). Median fluorescence intensity is a value that should be taken from a single log-normal distribution. In no case did we detect any changes induced by A in the soma (Figure 3I). ***p < 0.001; *p < 0.05; n.s, not significant; two-tailed t-tests. (J) Box and whisker graphs representing the total fluorescent intensity of the puromycin staining in III tubulin- and puromycin-positive somata within the range of 020 m from the nucleus (Soma) as also exemplified in (F). Georges, in Encyclopedia of Modern Optics, 2005. Local protein synthesis is a ubiquitous feature of neuronal pre- and postsynaptic compartments. Since experiments were always compared using a randomized block design (see Statistical Analyses), direct comparison between neurites imaged with different cameras is never performed. Second, it is assumed that the mAb of interest can bind its specific antigen in a monovalent fashion only and this is by no means certain unless a monovalent antibody can be purchased. When binarization of puromycin and SYTO labeling was performed for the same neurite, colocalization between RNA and protein was performed as follows: Process > Image Calculator > Image 1 (e.g., puromycin) AND Image 2 (e.g., SYTO; click create new window). 5 and 6: co-incubation with anisomycin and puromycin for 30 mins in DMSO- and A-treated cells, respectively. To maintain a proper function, each neuronal compartment needs to react temporally and spatially in an acute manner in order to rapidly adapt to changes in the environment. At this time, a scroll bar appears at the bottom of the picture. Figure 2 shows the comparison between simulation results and the flow cytometric data for A/Wisconsin/67/2005 (H3N2) for specific time points. For now, just try setting a threshold which you feel encompasses the red regions entirely, while minimizing the black regions that are included. No use, distribution or reproduction is permitted which does not comply with these terms. (2010). (A) Rat hippocampal neurons were grown for 9 DIV and were treated with DMSO (left panels) or A142 oligomers (right panels) for 24 h. Before fixing, cells were incubated with vehicle (-puro; neurites 1 and 2), with puromycin (+ puro; neurites 3 and 4) or with puromycin and anisomycin (+ anis + puro; neurites 5 and 6) for 30 mins. Uses of microlenses and waveguides in microfluidic systems have improved the detection limit in several applications. Nature 436, 10201024.
