Surface polypeptides of the Chinese hamster ovary cell; an immunochemical study

Antibodies elicited by the injection of live Chinese hamster ovary cells (CHO) into rabbits precipitated four major components from detergent extracts of CHO membranes. The four components, of molecular weights 200000, 125000, 95000 and 41000 daltons, corresponded to cell surface components identified by the lactoperoxide surface label technique.
