About CD179b
The preB cell receptor is found on the surface of proB and preB cells, where it is involved in transduction of signals for cellular proliferation, differentiation from the proB cell to the preB cell stage, allelic exclusion at the Ig heavy chain gene locus, and promotion of Ig light chain gene rearrangements. The preB cell receptor is composed of a membrane-bound Ig mu heavy chain in association with a heterodimeric surrogate light chain. This gene encodes one of the surrogate light chain subunits and is a member of the immunoglobulin gene superfamily. This gene does not undergo rearrangement. Mutations in this gene can result in B cell deficiency and agammaglobulinemia, an autosomal recessive disease in which few or no gamma globulins or antibodies are made. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

About RealBlue 780
BD Horizon RealBlue™ 780 (RB780) is part of BD's new product line of laser-specific fluorochromes which are designed to minimize cross laser excitaiton. This fluorochrome has a maximum excitation wavelength of 488nm and a maximum emission wavelength of 780nm. While RB780 is excited by the 488nm blue laser, it offers miminal cross-laser excitation off of the 561nm yellow/green laser. It is designed for use in Flow Cytometry and Spectral Flow Cytometry.
