Figure 1. Mouse PDGFRalpha kinase activity was measured in a radiometric assay using the following reaction conditions: 60 mM HEPES-NaOH, pH 7.5, 5 mM MgCl2, 5 mM MnCl2, 3 µM Na-orthovanadate, 1.2 mM DTT, 100 µM ATP, 250 µM FLT3 (Tyr589) biotinylated peptide and variable amount of Recombinant mouse PDGFRalpha. Reaction mixture incubated at room temperature for 10 minutes.
Figure 3. Dose dependence curve of mouse PDGFRalpha kinase activity: DELFIA® data generated using Phospho-Tyrosine Mouse mAb (P-Tyr-100) #9411 to detect phosphorylation of substrate peptide (#1305) by mouse PDGFRalpha kinase. In a 50 µl reaction, increasing amounts of mouse PDGFRalpha and 1.5 µM substrate peptide were used per reaction at room temperature for 30 minutes.

Staurosporine inhibition of mouse PDGFRalpha kinase activity: DELFIA® data generated using Phospho-Tyrosine Mouse mAb (P-Tyr-100) #9411 to detect phosphorylation of PDGFRalpha substrate peptide (#1305) by the mouse PDGFRalpha kinase. In a 50 µl reaction, 60 ng PDGFRalpha, 1.5 µM substrate peptide, 20 µM ATP and increasing amounts of staurosporine were used per reaction at room temperature for 30 minutes.
