ChEMBL Kinase Assay: Approximately 5-20 μg of purified GST-RET proteins were incubated with 1 mM ATP in 20 μL kinase buffer (10 mM Tris-HCl, 5 mM MgCl2, pH 7.4), at 30° C. for 30 minutes. The kinase reactions were terminated by boiling the samples in SDS-PAGE sample buffer. Samples were resolved on 10% acrylamide gels by SDS-PAGE followed by Western blotting. Phosphorylation was detected using a pan-phosphotyrosine pY99 antibody (available from Santa Cruz Biotechnology) or RET phospho-specific antibody (pY905, available from Cell Signaling, Beverly, Mass., USA).
