The antibody detects endogenous level of Zap-70 only when phosphorylated at tyrosine 493.
Purification
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatogramphy using non-phosphopeptide corresponding to the phosphorylation site.
Immunogen
Peptide sequence around phosphorylation site of pTyr493 (S-Y-Y (p) -T-A) derived from Human Zap-70. Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates.
