Zap-70(Phospho-Tyr493) Antibody

Description

Product Name Zap-70(Phospho-Tyr493) Antibody
Host Species Rabbit
Clonality Polyclonal
Purification Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
Applications WB IHC
Species Reactivity Hu Ms Rt
Specificity The antibody detects endogenous level of Zap-70 only when phosphorylated at tyrosine 493.
Immunogen Type Peptide-KLH
Immunogen Description Peptide sequence around phosphorylation site of tyrosine 493 (S-Y-Y(p)-T-A) derived from Human Zap-70.
Target Name Zap-70
Modification Phospho-Tyr493
Alternative Names 70 kDa zeta-associated protein; SRK; Syk-related tyrosine kinase; ZA70; ZAP-70

Background

Plays a role in T-cell development and lymphocyte activation. Essential for TCR-mediated IL-2 production. Isoform 1 induces TCR-mediated signal transduction, isoform 2 does not.
