Overview

Next-generation laser-specific flow cytometry research reagents


The family of BD Horizon RealYellow and BD Horizon RealBlue Reagents is bright, clean and laser specific to help streamline the path to your scientific discoveries.

 

Driven by next-generation BD dye technology and AI-guided fluorochrome selection to optimize spectral positioning, our new family of reagents is specially engineered to deliver reduced spillover to optimize resolution when used with other fluorochromes—helping to expand your experiments on both conventional and spectral flow cytometers.

When building assays, we are presented with hundreds of fluorochrome options and their different properties can make selection feel overwhelming. Check out our Fluorochrome Performance Chart with a handy cheat-sheet to help you prioritise clean fluorochromes and simplify your panel design.

Interview with Jochen Lamote, Head of VIB Flow Core



BD Biosciences sat down with Jochen Lamote to discuss his experience as a beta tester of flow cytometry reagents – including how BD Horizon RealBlue minimizes spillover and simplifies panel design.


Watch the interview to discover why the team at Vlaams Institute for Biotechnology (VIB) Flow Core would recommend BD Horizon RealBlueto their colleagues.

Introducing
BD Horizon RealYellow™ 586 (RY586) Reagents

BD Horizon RealYellow™ 586 (RY586) Reagents are now available as the first in the rapidly growing family of innovative, laser-specific fluorochromes. They are excited primarily by the 561-nm yellow-green laser and offer:

 

  • Minimal cross-laser excitation off the 488-nm blue laser
  • Bright fluorescence to detect low-expression surface and intracellular markers 

 

Conventional flow cytometry: Just as bright as PE, but with significantly less cross-laser excitation, RY586 reagents can be used instead of PE on conventional flow cytometers for more flexible panel design.

 

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.
