Diagnostic Utility

CD79a is a transmembranous protein that is expressed in all stages of B-cell maturation from lymphoblasts to plasma cells. It is a useful marker for B-cell lineage, and can complement anti-CD20 antibody for the diagnosis of low grade B-cell lymphoma after treatment with Rituximab.
