| Molecular Weight (kDa) | 70 Zap-70, 72 Syk |
| Source/Isotype | Rabbit |
| Application/Dilution | {Western Blotting: 1:1000, Immunofluorescence (Immunocytochemistry): 1:50, Flow Cytometry (Fixed/Permeabilized): 1:50} |
| Storage | Supplied in 10 mm sodium HEPES (pH 7.5), 150 mm NaCl, 100 µg/mL BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody. |
| Specificity/Sensitivity | Phospho-Zap-70 (Tyr319)/Syk (Tyr352) Antibody detects endogenous levels of Zap-70 only when phosphorylated at Tyr319. It cross-reacts with endogenous levels of Syk when phosphorylated at Tyr352. |
| Species Reactivity | Human |
| Source/Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr319 of human Zap-70. Antibodies are purified by protein A and peptide affinity chromatography. |
| Background | The Syk family protein tyrosine kinase Zap-70 is expressed in T and NK cells and plays a critical role in mediating T cell activation in response to T cell receptor (TCR) engagement (1). Following TCR engagement, Zap-70 is rapidly phosphorylated on several tyrosine residues through autophosphorylation and transphosphorylation by the Src family tyrosine kinase Lck (2-6). Tyrosine phosphorylation correlates with increased Zap-70 kinase activity and downstream signaling events. Expression of Zap-70 is correlated with disease progression and survival in patients with chronic lymphocytic leukemia (7,8).Phosphorylation of Tyr319 is required for the assembly of a Zap-70-containing signaling complex that leads to the activation of the PLC-gamma1-dependent and Ras-dependent signaling cascades in antigen-stimulated T cells (5,6). The orthologous Tyr352 residue in Syk is also involved in the association with PLC-gamma1 (9). |
