|W||H M R (C)||Endogenous||60||Rabbit|
Reactivity Key: H=Human M=Mouse R=Rat C=Chicken
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
Non-phospho-Src (Tyr527) Antibody detects endogenous levels of Src only when dephosphorylated at tyrosine 527. It may also cross-react with Yes, Fyn and Slk based on sequence similarity.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Tyr527 of human Src. Antibodies are purified by protein A and peptide affinity chromatography.
The Src family of protein tyrosine kinases, which includes Src, Lyn, Fyn, Yes, Lck, Blk, and Hck, are important in the regulation of growth and differentiation of eukaryotic cells (1). Src activity is regulated by tyrosine phosphorylation at two sites, but with opposing effects. While phosphorylation at Tyr416 in the activation loop of the kinase domain upregulates enzyme activity, phosphorylation at Tyr527 in the carboxy-terminal tail by Csk renders the enzyme less active (2).
