(A/B) x (C/D) = number of cellsper totalvolume in thesample tube (cell concentration as cells/uL). Calculating compensation requires controls including unstained, fluorescence minus one (FMOs), and single-color samples: Unstained samples and single-color controls are needed for setting parameters on spectral analyzers. See table below for information on antibodies usedand single-color control setup. This allows researchers to generate artificial positive and negative fluorescence populations that mimic the heterogeneous populations of cells in a sample that are negative or positive for a given marker. In order to live up to the Facility's mission of assuring quality control and reproducibility, facility staff will not assist with running samples when the necessary compensation controls are not provided by the investigator. Has anyone used the ArC Amine Reactive Compensation Bead Kit with The overlap or spillover of this emission signal can provide false results. An example of overlapping emissions from three fluorophores on the Invitrogen Flow Cytometry Panel Builder.Fluorescence signal may overlap if emission spectrums are broad and captured in a different detector specific for another fluorochrome. Compensation controls MUST match the exact experimental fluorochrome. In addition, the products listed above are not designed for dyes that discriminate dead cells (amine reactive dyes). 8999 BioLegend Way, San Diego, CA 92121 www.biolegend.com Background fluorescence should be the same for the positive and negative control (e.g, positive cells vs negative cells, or positive beads vs negative beads). Using a known concentration of beads mixed into the cell sample, the cell sample fluid volume passing through the instrument during acquistion can be established by counting the beads acquired during data acqusisition. Learn principles of compensation for your Flow Cytometry data analysis. The beads are stained as if they were cells using the same antibodies and fluorochromes that are used in the experiment, producing both a negative and bright positive population for each color. Cells stained with these products can also be run unfixed. (C)LIVE/DEAD Fixable Far Red dye stained beads were analyzed using 633 nm excitation, emission was collected with a 660/20 nm bandpass filter. By the end of this tutorial, you should be able to understand: What is compensation? They are designed for use in compensation with all fluorochromes excited by ultraviolet (355 nm) violet (405 nm), blue (488 nm), green (532 nm), yellow-green (561 nm), and red (633-640 nm) lasers. For US and Canada Customers only. All Rights Reserved The left histogram shows human PBMCs stained with anti-CD123 BV421 as a single color control. 77:1082. These variations result in leakage of donor dye fluorescence (e.g., PE fluorescence leaks from PE-Cy7) and diminished fluorescence emission strength (brightness) of the acceptor dye over time (e.g., Cy7 has reduced brightness as PE-Cy7 ages due to less energy transfer from PE). Learn more about setting up the compensation controls for your multicolor flow cytometry experiment with these helpful tips and tricks. Figure 3. We can give you a hand fitting it into your staining panel. Therefore it is recommended that a fluorescent viablity marker be added to most cell preparations before performing flow cytometry. . www.biolegend.com/apc-fire750. Improved for polymer dye use from violet laser. In that sense, it is widely recognized that the quality of your sample is directly reflected in the quality of your data.

Uncoated (negative) beads ensure standardization of the autofluorescence in each channel. Super Bright Polymer Dyes are sold under license from Becton, Dickinson and Company. The negative control (unstained cells) establishes the background fluorescence of the experimental samples and is used to set the baseline PMT (photomultiplier tube) voltages of the instrument. Those samples must be filtered with nylon meshto remove the aggregates or dispersed by some other method before running on the flow cytometer. Absolute Quantification of Plasma Membrane Receptors Via - Springer Compensation Beads (Cat. stem cell markers. No. All rights reserved. BioLegend Using Beads for Sample Compensation Do not use similar fluorophores because they are spectrally different and will not properly compensate. Resuspension of cells to be analyzed in media containing phenyl red should be avoided whenever possible. There are specialized tools for flow cytometry to monitor the number of dead cells and amount of tissue debris present. Overlaid plots shown are human peripheral blood mononuclear cells stained with the full 14-color panel, analyzed with unmixing matrix generated using BioLegend Compensation Beads (purple) or UltraComp eBeads Plus (orange). On full spectral flow instruments, they are used to set spectral unmixing parameters. The proper compensation controls include a negative control (unstained cells are recommended) and one tube each of cells (or beads) stained positively with each of the fluorochromes used in the experiment. This includes an increasing amount of colors that can be detected, which expands the numbers of parameters collected simultaneously, allowing for the study of many cell types in a mixed population sample.
