Note: Each spectral signature (Figures 1-3) generated displays the distribution of events as a function of intensity across the whole spectrum, for each laser. https://doi.org/10.1002/0471142956.cy0127s63, Sign up for Nature Briefing: Translational Research. A prodigy thats taking flow cytometry to the next level of performance and flexibility. Spectral cytometry on highly autofluorescent samples - Nature For Research Use Only. Careers. Figure 1. This information applies to selecting fluorophores for a panel if options are available, it is better to avoid fluorophores that cause a lot of spreading. Check out our resource library! This allows the use of more existing fluorophores that would otherwise be incompatible on a conventional flow cytometer and the expansion of immunophenotyping panels beyond 40 fluorescent parameters [17,18]. The second rule then explains that the PerCP-Cy5.5 will spread into BUV737 more than into BUV805 because it spills into the BUV737 detector more than the BUV805 detector. This differs from panels that examine a wide variety of cell types. Both systems employ standard fluidic and laser technologies that enable cell-by-cell spectral analysis. Like traditional flow cytometry, spectral flow cytometry enables live cellular analysis, which is critical when investigating numerous immunologicalareas. The information provided in the following tables is intended to guide researchers in their selection of fluorochromes for polychromatic panels when using the Cytek Aurora 3-laser system. Thanks for the very comprehensive explanations. the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in During spectral unmixing autofluorescence can be removed in order to better resolve and identify the true signal from the fluorescent probe of interest.

Flow cytometry is a technology that provides rapid multiparameter analysis of single cells or particles in suspension as they flow past single or multiple lasers. For Research Use Only. We have a growing collection of over 1000 monoclonal CF Dye primary and secondary antibody conjugates, as well as other bioconjugates. In this case, the spreading will only be an issue for a small number of cells. https://doi.org/10.1038/s43586-022-00156-0, DOI: https://doi.org/10.1038/s43586-022-00156-0. Cytometry Part A 97.10 (2020): 10441051. The spectral signature of a fluorophore is a result of multi-laser excitation. Cytek Aurora Training Part 1: Introduction to Full Spectrum Flow Cytometry As cellular autofluorescence can interfere with fluorescence detection in some protocols, spectral flow cytometry is capable of identifying and removing autofluorescence during analysis (see Figure 3 for an Invitrogen PrimeFlow RNA example). & Nalbant, A. In contrast, spectral flow cytometry uses multiple detectors to measure the full spectrum emission of every fluorophore across multiple lasers used in the system to create a more detailed signature for each fluorophore. Through this approach, fluorophores with near-identical peak emissions but different off-peak emissions maybe distinguished and used together in a panel.

We won't set optional cookies unless you enable them. However, based on this information dyes that emit at similar wavelengths can introduce spread into the other. Thermo Fisher Scientific. . For co-expressed markers, assign fluorophores with minimal spread into each other. Use any commercially available fluorochrome excited by the onboard lasers. However, each instrument has different laser configurations and optical sensitivity. Figure 1A shows that the BV785 marker has a clear positive and negative population. The panel presented here identifies CD4 T cells, CD8 T cells, regulatory T cells, T cells, NKT-like cells, B cells, NK cells, monocytes and dendritic cells. Limited by fluorophore spectral signature uniqueness, The bandwidth of emitted light delivered to the photodetectors, The number of detectors used per fluorophore, The algorithms employed to separate one fluorophore from another. MeSH Recent advancements in this field have led to the development of spectral flow cytometry, a rapidly growing technology with significantly enhanced multiplexing capabilities over conventional flow cytometry. 2). We use cookies on our website. Abstract. FerrerFont, Laura, et al. So the PerCPCy-5.5 signal will overlap on a number of other markers that you would not necessarily expect, including BUV737. Explore spectral flow cytometry reagents Explore the Bigfoot Spectral Cell Sorter. Cookie Policy. Staining was performed with CD4 primary antibody and subsequently labeled with secondary fluorophore. Assign them to a marker that is on a cell subset that does not co-express any other markers in the panel. Consequently, fluorophores with very similar emission spectra that were once impossible to separate by conventional flow cytometry methods (Fig. Now with spectral flow cytometry analysis researcher and scientists can investigate an increasing number of molecules of interest. Rev. In general, panel design for spectral flow cytometry follows the same principles as with conventional flow cytometry, including gating strategy, matching fluorophore brightness to antigen density, characterizing and minimizing spillover spreading error, and systematic use of experimental and technical controls. "Evaluating spectral cytometry for immune profiling in viral disease." While conventional flow cytometry uses compensation to correct for fluorescence spillover, spectral flow cytometry uses a process called unmixing to identify each fluorophore. With its intuitive optical design, compact footprint and upgradeability from 3 to 5 laser configurations, the Aurora system suits every laboratorys needs from simple to high complexity applications.

"The Evolution of Single-Cell Analysis and Utility in Drug Development." It was all very exciting! This is particularly useful for cell culture samples prone to high autofluorescence. Flow cytometry has evolved over many decades after the first commercial flow cytometers capable of measuring a single fluorescence parameter were introduced in the early 1970s [1]. However, it should be noted that pairing of very spectrally similar dyes like CF660C and CF660R is not optimal dye pairing practice and would not be recommended even for spectral flow. Development of a high-color flow cytometry panel for immunologic analysis of tissue injury and reconstruction in a rat model. For fluorophores that spread significantly into each other (typically pairs that cannot be distinguished by a conventional flow cytometer like APC and AF647), assign them to markers that are on different cell types so that a double positive population is not expected.

Unique spectral signatures for spectral flow cytometry Stable dyes that can be stored long-term without losing fluorescence as compared to tandem dyes NovaFluor dye technology NovaFluor dye technology Figure 1. Figure 2. In this case, no cells of interest will have the offending fluorophore(s) and spreading can be ignored. A Guide to Spectral Flow Cytometry Fluorophore Selection In any case, individual fluorescent reference controls are needed, similar to that of single-color controls in conventional flow cytometry, in order to deconvolute or unmix the spectral signatures in polychromatic panels. With up to five lasers, three scattering channels, and 64 fluorescence channels, the Aurora system is highly flexible, intuitive and ultra-sensitive.
