Description: Anti-CD79a is to identify B-cell linage (but not in myeloid or T cell lines) in formalin-fixed, paraffin embedded normal and neoplastic tissues using immunohistochemical (IHC) test methods. The CD79á polypeptide appears early in B-cell maturation at the pre-B-cell stage, and persists until the plasma cell stage, where it is found as an intracellular component. Anti-CD79á can be used for the immunohistochemical identification of cells of the B-cell lineage.
