ZAP70 Antibody (ZAP70/528) - IHC-Prediluted Summary

• Description: The prediluted antibody does not require any mixing, dilution, reconstitution, or titration; the antibody is ready-to-use and optimized for staining.
• Immunogen: Recombinant full-length human ZAP70 protein (Uniprot: P43403)
• Localization: Cell Surface and Cytoplasmic
• Marker: Chronic Lymphocytic Leukemia Marker
• Specificity: ZAP70 is a 70kDa protein tyrosine kinase found in T-cells and natural killer cells. Control of this protein translation is via the IgVH gene. ZAP70 protein is expressed in leukemic cells of approximately 25% of chronic lymphocytic leukemia (CLL) cases as well.Anti-ZAP70 expression is an excellent surrogate marker for the distinction between the Ig-mutated (anti-ZAP70 negative) and Ig-unmutated (anti-ZAP70 positive) CLL subtypes and can identify patient groups with divergent clinical courses. The anti-ZAP70 positive Ig-unmutated CLL cases have been shown to have a poorer prognosis.
• Isotype: IgG2a Kappa
• Clonality: Monoclonal
• Host: Mouse
• Gene: ZAP70
• Purity: Protein A or G purified

Applications/Dilutions

• Dilutions:
  • Immunohistochemistry
  • Immunohistochemistry-Paraffin
• Application Notes: Hu-chromosome location: 2q12 Immunohistochemistry-Paraffin 0.5 - 1 ug/ml for 30 minutes at RT; Staining of formalin-fixed tissues requires boiling tissue sections in 10mM Tris with 1mM EDTA, pH 9.0, for 10 - 20 min followed by cooling at RT for 20 minutes. The 7mL size is a pre-diluted size and no additional dilutions are required before using this item for the intended application.
• Theoretical MW: 70 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background

Zap-70, a Syk-family protein tyrosine kinase, plays a critical role in mediating T cell signal transduction in response to T cell receptor (TCR) activation (1). TCR-mediated activation of the Src-family kinases, Lck and Fyn, results in tyrosine phosphorylation of the TCR zeta and CD3 chains. These domains serve as targets for binding of ZAP-70 via its tandem SH2 domains. This binding correlates with activation of ZAP-70, a critical event in T cell activation (2). Following TCR engagement, ZAP-70 is phosphorylated on several tyrosine residues, presumably by two mechanisms: an autophosphorylation and a trans-phosphorylation by the Src-family tyrosine kinase, Lck. Phosphorylation of Tyr319 is required for full activation and increased positive downstream regulation by ZAP-70 (3).
