It is primarily expressed in T cells and natural killer (NK) cells, but is also detectable in mast cells and basophils. ZAP-70 is also expressed in normal pro/pre B cells but not in normal mature B cells. ZAP-70 is expressed in B cells in a subset of chronic lymphocytic leukemias (CLL) closely associated with an unmutated configuration of the immunoglobulin heavy-chain variable region (IgVH) genes. The precise functional significance of ZAP-70 in this subset of CLL B cells is unknown. Some data indicates that expression of ZAP-70 in CLL allows more effective IgM signaling in CLL B cells, which could explain the disease progress. Also, some other B-cell neoplasms and T-cell neoplasms express ZAP-70.;Description:Mouse Anti-Human ZAP70 Monoclonal Antibody;Host Species:Mouse;Species Reactivity:Human;Clone#:2F3.3;Isotype:IgG2a, kappa;Application:IHC;Storage:Store antibody products at 2-8°C.
