Zap-70 (99F2) Rabbit mAb #2705
|W IP IHC-P F||H M||Endogenous||70||Rabbit IgG|
Reactivity Key: H=Human M=Mouse
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
Zap-70 (99F2) Rabbit mAb detects endogenous levels of total Zap-70.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding the amino-terminus of human Zap-70.
Western blot analysis of extracts from Jurkat cells, starved for 16 hours and either untreated or H2O2-treated (2 mM for 3 minutes), using Zap-70 (99F2) Rabbit mAb.
Immunofluorescent staining of paraffin-embedded human tonsil, showing Zap-70 localized with T-cells surrounding a germinal center, using Zap-70 (99F2) Rabbit mAb (green) and anti-CD3 (T-cell marker) (red). DAPI stain is shown in blue.

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).
