Biolegend, 693504, PE anti-ZAP-70 Antibody, 100tests

ZAP-70 is a 70kD protein expressed near the surface membrane of T-cells and NK cells. It is part of the intracellular signaling mechanism of the T-cell receptor, and plays integral role in T-cell signaling where it interacts with CD3-ζ to phosphorylate transmembrane protein LAT, which facilitates the binding of many signaling proteins. ZAP-70 plays a key role in the activation of T-cells, and their subsequent proliferation, differentiation, and production of cytokines in response to varied stimuli. It is used clinically as a prognostic marker helping differentiate the various types of chronic lymphocytic leukemia (CLL).

Application Notes: CD3, CD19, and CD56 co-staining indicates that this clone does not bind B-cells and will not bind Syk. Clone A16043B cross-reacts with mouse species.NOTE: For flow cytometric staining with this clone, True-Nuclear™ Transcription Factor Buffer Set (Cat. No. 424401) offers improved staining and is highly recommended. This clone, A16043B, recognizes both non-phosphorylated ZAP-70 and phosphorylated forms of ZAP-70.
RRID: AB_2632836 (BioLegend Cat. No. 693503) AB_2632837 (BioLegend Cat. No. 693504)
Structure: Protein tyrosine kinase, contains two SH2 domains, 70 kD.
Distribution: T cells, NK cells, and B-cell chronic lymphocytic leukemia (B-CLL).
Function: Signal transduction, associates with the T-cell antigen receptor zeta chain tyrosine-based activation motif when phosphorylated. Defects in ZAP70 causes selective T cell defect.
Ligand/Receptor: Binds to CD3 zeta chain, also associates with a variety of proteins including SLA, Fyn, RasGap, Lck, Vav1, and Shc.
