BD Horizon™ Red 718 Reagents

BD Horizon™ Red 718 (R718) is an innovative small-molecule fluorochrome developed exclusively for BD Biosciences. It provides improved sensitivity and resolution of low-density markers and intracellular targets. R718 is excited by the red laser with an emission maximum of 718 nm and can be detected by the same filter as Alexa Fluor™ 700.


BD Horizon™ Red 718 Reagents are specially designed to serve as alternatives to Alexa Fluor™ 700 or APC-R700.


BD Horizon™ Red 718 Reagents offer:

  • Greater brightness and resolving power than Alexa Fluor™ 700 for both surface and intracellular markers
  • Reduced background staining compared to Alexa Fluor™ 700 and APC-R700
  • Minimal spread into the APC channel
  • A broad portfolio of conjugates through BD OptiBuild™ On-Demand Reagents
  • Lot-to-lot consistency to reduce risk of data variability


In addition, R718 is compatible with a variety of buffers including BD FACS™ Lysing Solution and BD Pharm Lyse™ Lysing Buffers


BD Horizon™ Red 718 Reagents have the potential to enhance your flow cytometry panel's performance.
