CD79a first appears at the 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, B‑cell lines, B‑cell lymphomas, and in some myelomas. It is not present in myeloid cells or T‑cells.
