BD FACSuite™ CS&T research beads (CS&T research beads) are designed for use on BD™ flow cytometers running BD FACSuite™ software. The beads enable the software to automatically run performance QC (daily) and characterization QC (every six months). CS&T research beads are dyed with fluorochromes which are excited by the cytometer’s lasers. The beads emit fluorescence in detectors used for the following fluorochromes.
