The StarBright Violet 760, StarBright UltraViolet 575, and StarBright UltraViolet 605 dyes are conjugated to highly validated antibodies and offer improved brightness with narrow excitation and emission profiles for precise resolution, according to the announcement.

The dyes, excited by violet (405 nm) and ultraviolet (355 nm) lasers, are compatible with the Bio-Rad ZE5 Cell Analyzer and S3e Cell Sorter, as well as most flow cytometers and a variety of experimental protocols, without the need for special buffers, the company said.

"The continued expansion of the Bio-Rad StarBright dye portfolio, currently totaling 17 dyes, nine of which are StarBright Violet dyes, gives researchers greater flexibility and choice when designing flow cytometry panels, by providing high-performance dyes excitable at a range of wavelengths," Mike Blundell, PhD, Bio-Rad Product Manager, Flow Cytometry, Life Science Group, said in a statement. "The exceptional brightness and unique profile of the dyes delivers enhanced resolution of rare populations and low-density antigens."
