Bio-Rad Launches First StarBright Red Dye and Extends Range of Antibody Markers Conjugated to StarBright Dyes to Enhance Multiplex Flow Cytometry and Research Capabilities

With 29 additional targets the range also includes dog, cow and pig targets to support translational models in veterinary immunology research

29 August 2023 -- California, US -- Bio-Rad Laboratories Inc (NYSE: BIO and BIOb), a global leader in life science research and clinical diagnostic products, announced the launch of the 29th StarBright Dye, StarBright Red 670 and an expansion of its current range with 29 additional highly validated antibodies conjugated to StarBright Blue 700 and StarBright Violet 610 Dyes. Including additional human and mouse targets and introducing dog, cow and pig targets, the new range provides greater choice and flexibility in conventional and full-spectrum multicolour flow cytometry panels, expanding research capabilities across veterinary immunology research.

Offering exceptional brightness with narrow excitation and emission profiles for precise resolution, Bio-Rad’s line of StarBright Dyes provides researchers with validated flow antibodies against key immunology targets conjugated to proprietary fluorescent nanoparticles. StarBright Dyes are compatible with the Bio-Rad ZE5 Cell Analyser and S3e Cell Sorter, as well as most flow cytometers and experimental protocols, without the need for special buffers. Minimal lot-to-lot variation ensures reproducible and consistent staining – the dyes are resistant to photobleaching with no loss of signal in fixation.

The additional 29 antibody markers will soon be available on all StarBright Dyes.

“Now totalling 29 dyes for the 355, 405, 488, 561 and 640 nm lasers, the Bio-Rad StarBright Dye range is currently the largest series of dyes for conventional and full spectrum flow cytometry,” said Mike Blundell, PhD, product manager, Flow Cytometry, Life Science Group, Bio-Rad. “By extending our existing portfolio of 35 antibody markers to include another 29 human, mouse and now cow, dog and pig targets, we can offer our customers greater flexibility and choice when designing multicolour flow cytometry panels, including for translational and immunological research in veterinary species.”
