Reacts with ZAP-70 expressed in T cells, natural killer cells, pro/pre B cells but not in normal mature B cells. The antibody is a useful aid for classification of a subset of chronic lymphocytic leukemias (CLL). In CLL, ZAP-70 expression is closely associated with an unmutated configuration of the immunoglobulin heavy-chain variable region (IgVH) genes (1).

In Western blotting of whole cell lysates of normal peripheral blood mononuclear cells, the antibody labels a band corresponding to ZAP-70 (2). In Western blotting of whole cell lysates of CD19-positive purified leukemia cells from patients with Ig-unmutated and Ig-mutated CLL, the antibody labels a band corresponding to ZAP-70 in the Ig-unmutated CLL samples, whereas no band is observed in the Ig-mutated CLL samples (2). In Western blotting of cell lysates of Jurkat cells (T-lymphoblastic cell line), the antibody labels a band of 70 kDa protein (6). In Western blotting of cell lysates of A431 cells (carcinoma cell line), no band is observed (6). See package insert for reference(s).
