The phosphorylation of mixed casein by casein kinase II shows resistance on .beta. casein after partial alkali hydrolysis of the proteins separated by gel electrophoresis. This property is specific for casein kinase II among the protein kinases tested and can be used for casein kinase II detection in biological extracts and for characterization of purified casein kinase II.
