Product Description

This peptide is used to specifically block Src Antibody #2108 and Src (36D10) Rabbit mAb #2109 reactivity.


Quality Control

The quality of the peptide was evaluated by reversed-phase HPLC and by mass spectrometry. The peptide blocks Src Antibody #2108 and Src (36D10) Rabbit mAb #2109 signal in dot blot.

Product Usage Information

Use as a blocking reagent to evaluate the specificity of antibody reactivity in dot blot protocols.


Storage: Supplied in 20 mM potassium phosphate (pH 7.0), 50 mM NaCl, 0.1 mM EDTA, 1 mg/ml BSA and 5% glycerol. 1% DMSO. Store at –20°C.

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).
