Description
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
