Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Protocols

Specificity / Sensitivity

Src (L4A1) Mouse mAb detects endogenous levels of Src proteins. The antibody does not cross-react with other proteins.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a recombinant fusion protein containing the corresponding amino acid residues 1-110 of human Src.

Western Blotting

Western Blotting

Western blot analysis of cell extracts from various cell lines, using Src (L4A1) Mouse mAb.

Background

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).
