Flow Cytometry Antibodies

Illuminate your research with RayBright® Technology

Different cell populations can be distinguished from one another in a complex sample using flow cytometry and antibodies conjugated to non-overlapping fluorophores.

RayBiotech is proud to offer RayBright dyes with excellent brightness, covering most of the common emission colors of similar dyes. The tables below provide the excitation and emission spectra of our RayBright fluorochromes and their equivalent dyes.
