The StarBright UltraViolet 510, StarBright UltraViolet 665, and StarBright UltraViolet 795 Dyes Offer Exceptional Brightness with Narrow Excitation and Emission Profiles to Support Multiplex Panels

HERCULES, Calif.–April 19, 2022–Bio-Rad Laboratories, Inc. (NYSE: BIO and BIOb), a global leader of life science research and clinical diagnostic products, today introduced three StarBright™ Dyes designed for use with a 355 nanometer UV laser in flow cytometry applications. StarBright UltraViolet 510, 665, and 795 Dyes offer exceptional brightness with narrow excitation and emission profiles for precise resolution, expanding Bio-Rad’s range to provide greater flexibility in multicolor flow cytometry panels.

Bio-Rad’s line of StarBright Dyes offers researchers unique fluorescent nanoparticles conjugated to highly validated flow antibodies, which are compatible with most experimental protocols and flow cytometers, including Bio-Rad’s ZE5 Cell Analyzer and S3e Cell Sorter. The dyes are resistant to photobleaching and are highly stable with no loss of signal in fixation, and minimal lot-to-lot variation helps to ensure consistent staining and deliver reliable results.

“We are proud to add three new dyes to Bio-Rad’s StarBright UltraViolet portfolio, following its launch last year, and are now better positioned to support researchers with their flow cytometry workflows by providing a range of high-performance dyes excitable by the 355 nanometer UV laser to existing alternatives,” said Mike Blundell, PhD, Bio-Rad Product Manager, Flow Cytometry, Life Science Group. “The unrivaled brightness of the dyes enables enhanced resolution of low-density antigens and rare populations while maintaining consistent and reproducible staining without the need for special buffers.”
