Abstract

A murine monoclonal anti-protein kinase CK2 beta antibody was isolated and characterized. The antibody detects 1 pmol of purified recombinant CK2 beta-subunit after analysis on SDS-PAGE. Alternatively undenatured CK2 beta-subunit was detected by an ELISA assay either as recombinant CK2 beta-subunit or in the CK2 holoenzyme (alpha 2 beta 2). Here, concentrations of the first antibody of 1 ng/ml still allowed the detection of the subunit. Immunoblotting of crude cellular extracts from various tissue cultures (man, mouse, and hamster), from human tumors, and the nonneoplastic tissue allowed the detection of the CK2 beta-subunit. The detected epitope of this antibody was, as determined by the epitope analysis technique, 123GLSDI127.
