Bio-Rad Laboratories Annexin V StarBright conjugates

Bio-Rad Laboratories has launched annexin V conjugated to eight of the company’s StarBright Dyes: SBUV400, SBUV795, SBV440, SBV515, SBV790, SBB675, SBB765 and SBY800. The Annexin V StarBright conjugates support detection of early apoptotic cells by flow cytometry, offering an increased range of fluorophore options.

The annexin V conjugates provide researchers with a variety of choices, especially important when including apoptosis detection in multicolour immunophenotyping panels in both conventional and full spectrum flow cytometry. The conjugates enable full utilisation of all the common laser lines found in flow cytometers such that common viability dye and fluorescent protein emission wavelengths can be avoided. This, combined with the narrow excitation and emission of StarBright Dyes, should reduce spillover and spreading to provide high-resolution data.
