CST's PathScan® Phospho-Zap-70 (Tyr319) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of phospho-Zap-70 (Tyr319) 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, Phospho-Zap-70 (Tyr319) Ab is added to detect the captured phospho-Zap-70 (Tyr319) 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 phospho-Zap-70 (Tyr319) protein.
