anti-CD79a (C-term) (human), Rabbit Monoclonal (RM297)

Product description: Recombinant Antibody. This antibody reacts to human CD79a. Applications: WB, IHC. Source: Rabbit. Liquid. 50% Glycerol/PBS with 1% BSA and 0.09% sodium azide. CD79a is a disulphide-linked heterodimer together with CD79b. CD79a plays multiple and diverse roles in B cell development and function. The CD79a/b heterodimer associates non-covalently with the immunoglobulin heavy chain through its transmembrane region, thus forming the BCR along with the immunoglobulin light chain and the pre-BCR when associated with the surrogate light chain in developing B cells. Association of the CD79a/b heterodimer with the immunoglobulin heavy chain is required for surface expression of the BCR and BCR induced calcium flux and protein tyrosine phosphorylation. The CD79a protein is present on the surface of B-cells throughout their life cycle, and is absent on all other healthy cells, making it a highly reliable marker for B-cells in immunohistochemistry. The protein remains present when B cells transform into active plasma cells, and is also present in virtually all B-cell neoplasms, including B-cell lymphomas, plasmacytomas and myelomas. It is also present in abnormal lymphocytes associated with some cases of Hodgkins disease. Because even on B cell precursors, it can be used to stain a wider range of cells compared to the alternative B cell marker CD20 and is often used together in immunohistochemistry panels.
