Human PBMCs were stained with two sets of reagents, moderately similar CD4 RB545 and CD127 FITC, and highly similar CD4 FITC and CD127 BB515. Co-expressed markers were selected to demonstrate impact of spectral unmixing with different levels of similarity. Resolution was impacted when reagents were highly similar, shown in bottom set of CD4 FITC and CD127 BB515. Samples were acquired on the BD FACSymphony™ A5 SE Cell Analyzer and spectrally unmixed with FlowJo™ Software.

Spectral flow cytometry: With a distinct spectral profile from PE, RY586 reagents can be used with PE on spectral flow cytometers to increase parameters for deep scientific insights.

Excellent Resolution

Generate reliable data that clearly resolve even the most challenging cell populations by leveraging bright, clean fluorochromes that minimize spillover and background.

Flexible Panel Design

Maximize panel design options for both conventional and spectral flow cytometry by using reagents that deliver minimal cross-laser excitation in hundreds of antibody specificities.

High-Dimensional Analysis

Reveal more insights from the same sample by expanding the utility of blue and yellow-green laser channels with reagents that enable the simultaneous use of more detectors.
