Western Blotting
Western blot analysis of extracts from Jurkat cells, starved for 16 hours, and treated with 2 mM H2O2 or with calf intestinal alkaline phosphatase (CIP), using Phospho-Zap-70 (Tyr319)/Syk (Tyr352) Antibody (upper) or control Zap-70 Antibody #2702 (lower).
Western Blotting
Western blot analysis of extracts from Ramos cells, untreated or treated with anti-IgM (12 µg/ ml for 2 minutes), hydrogen peroxide (10 mM for 2 minutes) or lambda phosphatase, using Phospho-Zap-70 (Tyr319)/ Syk (Tyr352) Antibody.
Flow Cytometry
Two-color flow cytometric analysis of Jurkat cells, untreated (left) or anti-CD3 activated (right), using Phospho-Zap-70 (Tyr319)/Syk (Tyr352) Antibody and Phospho-p44/42 MAPK (Thr202/Tyr204) (E10) mAb #9106. Anti-CD3 activation increases the intensity of label with both antibodies.
Flow Cytometry
Flow cytometric analysis of Jurkat cells, untreated (blue) or CD3 treated (green), using Phospho-Zap70 (Tyr319)/Syk (Tyr352) Antibody compared to a nonspecific negative control antibody (red).
IF-IC
Immunofluorescent analysis of Jurkat cells, CD3-treated (left) or untreated (right), using Phospho-Zap-70 (Tyr319)/Syk (Tyr352) Antibody (red). Blue pseudocolor = DRAQ5™ (fluorescent DNA dye).

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 (CLL) (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).
