Bio-Rad Laboratories, a global provider of life science research and clinical diagnostics products, has introduced a new range of StarBright dyes to provide greater choice and flexibility for spectral flow cytometry in immunology research. The first dye in the series, StarBright UltraViolet700 (SBUV700), is now available, with further dyes to follow in the coming months.

Conjugated to validated immunology antibodies against 46 markers found in common immunological samples, including 13 new markers, the range has been developed specifically for spectral flow cytometry. The dyes exhibit unique spectra and maximal emission peaks, making them suited for multiplexing panels.

Bio-Rad’s StarBright dyes provide high brightness and narrow excitation and emission profiles, giving researchers more options for panel design with reduced spreading and increased resolution. They can be incorporated into new or existing experiments and are compatible with the Bio-Rad ZE5 Cell Analyzer, as well as most other flow cytometers, cell sorters, and spectral instruments.

“We continue to expand our StarBright dye range of fluorescent markers for flow cytometry, which now includes over 30 dyes,” said Hilary Mavor, marketing director, life science group, Bio-Rad Laboratories.

“The new range, beginning with launch of the new StarBright UltraViolet700 dye, provides our customers with greater options when designing spectral flow cytometry panels, allowing for novel dye combinations and the creation of larger multicolour panels of increased complexity.”
