CD79a Monoclonal Antibody (ZL7-4), Invitrogen™

Description

MA1-81093 reacts with human CD79a-positive cells by flow cytometry and ELISA specific for a fusion protein of CD79a-Fc. This clone has been reported to be useful in distinguishing B-CLL from mantle cell lymphoma in flow cytometric assays. For FACS analysis, use 10 μL of the suggested working dilution to label 1x10^6 cells in 100 μL. Mouse anti Human CD79a antibody, clone ZL7-4 recognizes the human B-cell antigen receptor complex-associated protein alpha chain, also known as MB-1 membrane glycoprotein or CD79a.

CD79a is a disulphide-linked heterodimer that includes B29 (CD79b) polypeptide. CD79a is a B lymphocyte antigen receptor with an antigen-specific surface component Ig (immunoglobulin) that associates with Ig-alpha and Ig-beta, necessary elements for the expression and function of the B-cell antigen receptor. CD79a first appears at pre-B cell stage and persists until the plasma cell stage where it is found as an intracellular component. CD79a is found in the majority of acute leukemias of precursor B cell type, in B cell lines, B cell lymphomas, and in some myelomas. It is not present in myeloid or T cell lines. Diseases associated with CD79a include Agammaglobulinemia 3 and Agammaglobulinemia, Non-Bruton type.
