    Product Information

    Product Description

    CST's PathScan® Total Zap-70 Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of total Zap-70 protein. A Zap-70 Mouse mAb has been coated onto the microwells. After incubation with cell lysates, both phospho- and nonphospho-Zap-70 proteins are captured by the coated antibody. Following extensive washing, Zap-70 Antibody is added to detect the captured phospho- and nonphospho-Zap-70 protein. Anti-rabbit IgG, HRP-linked antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of optical density for this developed color is proportional to the quantity of total Zap-70 protein.

    *Antibodies in this kit are custom formulations specific to kit.

    Protocol

    Specificity / Sensitivity

    CST's PathScan® Total Zap-70 Sandwich ELISA Kit detects endogenous levels of Zap-70 enzyme. As shown in Figure 1, using this Sandwich ELISA Kit #7171, a significant induction of Phospho-Zap-70 (Tyr319) in Jurkat cells treated with hydrogen peroxide is detected. However, the level of Zap-70 (either untreated or treated), detected by the Total Zap-70 Sandwich ELISA Kit #7172, remains unchanged. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

    Background

    The Syk family protein tyrosine kinase Zap-70 is expressed in T and NK cells and plays a critical role in mediating T cell activation in response to T cell receptor (TCR) engagement (1). Following TCR engagement, Zap-70 is rapidly phosphorylated on several tyrosine residues through autophosphorylation and transphosphorylation by the Src family tyrosine kinase Lck (2-6). Tyrosine phosphorylation correlates with increased Zap-70 kinase activity and downstream signaling events. Expression of Zap-70 is correlated with disease progression and survival in patients with chronic lymphocytic leukemia (7,8).
