About CD23
The protein encoded by this gene is a B-cell specific antigen, and a low-affinity receptor for IgE. It has essential roles in B cell growth and differentiation, and the regulation of IgE production. This protein also exists as a soluble secreted form, then functioning as a potent mitogenic growth factor. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.[provided by RefSeq, Jul 2011]

About Brilliant Ultraviolet 395
Brilliant™ UltraViolet 395 (BUV395) is a UV-emitting base polymer dye that can be excited by the 355 nm ultraViolet laser and collected using a 379/28 bandpass filter. BUV395 has an excitation peak at 348 nm and an emission peak at 395. BUV395's fairly unique excitation and emission spectrum causes relatively little spillover into other common detectors and conflicts with very few other commonly used fluorophores. An alternative to BUV395 for flow cytometry is StarBright UltraViolet 400. This dye is part of the Brilliant™ UltraViolet dye family, developed and sold by BD Biosciences. These dyes were optimized for use with multicolor flow cytometry. BUV395 forms the backbone of the family, as all other members are tandems that use it as the acceptor, thus making them excitable by the same 355 nm UV laser.
