Biolegend, 693502, Purified anti-ZAP-70 Antibody, 100μg

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).
100μg
Verified Reactivity: Human, Mouse
Antibody Type: Monoclonal
Host Species: Mouse
Immunogen: Human ZAP 70 peptide phosphorylated at Y493. Complete Freund’s adjuvant.
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography.
Concentration: 0.5 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C.
Application: ICFC - Quality tested
Recommended Usage: Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.125 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
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. This clone, A16043B, recognizes both non-phosphorylated ZAP-70 and phosphorylated forms of ZAP-70.
RRID: AB_2810698 (BioLegend Cat. No. 693502)
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.
