Description_x000D_ General description_x000D_ Monoclonal Anti-ZAP-70 (mouse IgG1 isotype) is derived from the hybridoma 1E7.2 produced by the fusion of mouse myeloma cells and splenocytes from mice. ZAP-70 is a protein tyrosine kinase of the Syk family that is localized exclusively to the cytosol of T cells and natural killer cells._x000D_ Immunogen_x000D_ The immunogen sequence is conjugated to KLH._x000D_ peptide corresponding to amino acids 282-307 of human ZAP-70._x000D_ Application_x000D_ Monoclonal Anti-ZAP-70 antibody has been used in_x000D_ • enzyme linked immunosorbent assay (ELISA)_x000D_ • immunoblottin_x000D_ • flow cytometry_x000D_ • immunoprecipitation_x000D_ • immunocytochemistry_x000D_ Monoclonal Anti-ZAP-70 antibody is suitable for use in western blot (0.5-1.0 μg/mL using Jurkat cell extract), flow cytometry, immunocytochemistry, immunoprecipitation, microarray and indirect ELISA._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ ZAP-70 is a protein tyrosine kinase that is expressed in natural killer cells and T-lymphocytes. ZAP-70 interacts with the zeta chain of the T cell antigen receptor (TCR) and subsequently modulates cell signaling . Lack of ZAP-70 leads to an absence of antigen-specific response and also causes impaired T cell differentiation . Anti-ZAP-70 antibody is specific for human and mouse ZAP-70 (approx. 70 kDa)._x000D_ Zeta-chain-associated protein kinase70 (ZAP-70) is required for T-cell activation and is activated by(Tyrosine protein kinase) Lck-mediated phosphorylation of its tyrosine residues. Mutation of the gene that creates a defective ZAP-70 results in severe combined immunodeficiency syndrome (SCID).
