Kinase Assay - DELFIA Image 2

Figure 3. Dose dependence curve of Src kinase activity: DELFIA® data generated using Phospho-Tyrosine Mouse mAb (P-Tyr-100) #9411 to detect phosphorylation of substrate peptide (#1366) by Src kinase. In a 50 µl reaction, increasing amounts of Src and 1.5 µM substrate peptide were used per reaction at room temperature for 30 minutes. (DELFIA® is a registered trademark of PerkinElmer, Inc.)

Figure 5. Staurosporine inhibition of Src kinase activity: DELFIA® data generated using Phospho-Tyrosine Mouse mAb (P-Tyr-100) #9411 to detect phosphorylation of Src substrate peptide (#1366) by Src kinase. In a 50 µl reaction, 50 ng Src, 1.5 µM substrate peptide, 20 µM ATP and increasing amounts of staurosporine were used per reaction at room temperature for 30 minutes.

The kit provides a means of performing kinase activity assays with recombinant human Src kinase. It includes active Src kinase (supplied as a GST fusion protein), a biotinylated peptide substrate and a phospho-tyrosine antibody for detection of the phosphorylated form of the substrate peptide.

Molecular Formula:

Peptide substrate, Biotin-peptide: 1830 Daltons. GST-Src Kinase: 90 kDa.

Peptide Core Sequence:

GIY*DV

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).
