CD79a (EP82)

Anti-CD79a recognizes the Ig-alpha protein of the B-cell antigen component of the B-lymphocyte antigen receptor.1-3 Anti-CD79a is generally used to complement anti-CD20. This antibody will stain many of the same lymphomas as anti-CD20, but also is more likely to stain precursor B-cell lymphoblastic lymphoma/leukemia.2 Anti-CD79a also stains more cases of plasma cell myeloma and occasionally some types of endothelial cells as well.
