Summary: c-Src Kinase (Human) Assay/Inhibitor Screening Assay Kit is a single-site, non-quantitative immunoassay for kinase activity of recombinant catalytic domain of c-Src. Plates are pre-coated with a newly designed "Tyrosine kinase-binding module-1", which can easily bind recombinant catalytic domain of c-Src, subsequently activate c-Src kinase activity on a microtiter plate. The detector antibody is PY-39, an antibody that specifically detects the phosphotyrosine residue on recombinant catalytic domain of c-Src itself, which means that this kit measures the intensity of autophosphorylation of c-Src catalytic domain.
