CD79a Monoclonal Antibody (HM57), Invitrogen™

Description

Membrane permeabilization is required for flow cytometry applications. For FACS analysis, use 10 µL of the suggested working dilution to label 1x10^6 cells in 100 µL. A suggested positive control for immunohistochemical applications is human tonsil. This product requires antigen retrieval using heat treatment prior to staining of paraffin sections. Mouse anti Human CD79a antibody, clone HM57 recognizes an epitope within the cytoplasmic domain of 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.
