Bio-Rad Laboratories, Inc., a global leader in life science research and clinical diagnostics products, has announced the introduction of a new range of StarBright Dyes, providing greater choice and flexibility for spectral flow cytometry in immunology research. The first dye in the series, StarBright UltraViolet700 (SBUV700), is now available, marking the start of a broader rollout over the coming months.

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

Bio-Rad’s range of StarBright Dyes provides exceptional brightness and features narrow excitation and emission profiles, offering researchers more options for panel design with minimized spreading and increased resolution. StarBright Dyes can be easily incorporated into new and 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 multicolor panels of increased complexity.”

Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays.

Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.MultiplexFluorescent Dyes
