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 Analyser and spectrally unmixed with FlowJo™ Software.

Performance

BD Horizon RealYellow™ 775 Reagents are very bright with reduced spillover and monocyte background

Normalised emission profile of RY775, PE-Cy7 and StarBright™ Yellow 800

RY775 shows reduced spillover spread into the corresponding blue detectors.

RY775 provides improved nonspecific binding.

Applications

1/3

"BD Horizon RealYellow™ 586 (RY586) Reagents look like the best alternative for PE and will simplify panel design on conventional flow cytometers. They can also be an additional dye for spectral panel design.”

Gert Van Isterdael, PhD

“The RB780 fluorochrome fits very well into the spectral gap of dyes primarily excited by the blue laser and can be separated beautifully from PE-Cy7 on instruments with blue and yellow-green lasers.”

“I’m really excited about the BD Horizon RealBlue^™ 780 Dye. The staining we have done so far with Ki-67 and Granzyme B can be seen very clearly, even with high dilutions.”
