ZAP70 antibodies are significant for flow cytometry due to their role in detecting the ZAP70 protein, a tyrosine kinase involved in T-cell receptor (TCR) signaling. These antibodies are crucial for studying T-cell activation, differentiation, and signaling pathways. ZAP70 is also a prognostic marker in chronic lymphocytic leukemia (CLL), where its expression correlates with disease aggressiveness. Examine the supplier's provided validation data when comparing ZAP70 antibodies for flow cytometry. Also look for application-specific recommendations, such as dilutions, protocols, sample types, and other helpful usage notes.
