Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IHC-P=Immunohistochemistry (Paraffin),


Species predicted to react based on 100% sequence homology: Chicken,

Specificity / Sensitivity

Phospho-Src (Tyr527) Antibody detects endogenous levels of Src only when phosphorylated at Tyr527. The antibody may cross-react with other Src family members such as Yes, Fyn, Fgr and Yrk when phosphorylated at the equivalent sites.

Phospho-Src (Tyr527) Antibody兔多抗能识别内源性Tyr527位点磷酸化的Src蛋白水平。该抗体可能与其他Src家族成员发生交叉反应,如相同位点磷酸化的Yes, Fyn, Fgr 和Yrk 。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr527 of human Src. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

Western blot analysis of extracts from NIH/3T3 cells, using Phospho-Src (Tyr527) Antibody (A,B) or v-Src antibody (C,D). The phospho-specificity of the antibody was confirmed by treating the membrane with calf intestinal alkaline phosphatase (CIP) (B,D) after Western transfer.

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).

Src家族蛋白酪氨酸激酶包括Src, Lyn, Fyn, Yes, Lck, Blk, Hck, 对调节真核细胞的生长和分化很重要(1)。Src的活性是通过两个酪氨酸位点的磷酸化来调控的,但是这两者的调控效应相反。激酶结构域的活化环中的Tyr416位点的磷酸化,能够上调酶活性;而蛋白羧基端尾部Tyr527位点被Csk磷酸化后,则会使酶的活性降低(2)。
