immunoprecipitation of antigens from wt-infected kb cells followed by sds-polyacrylamide gel electrophoresis of precipitated proteins revealed that a major polypeptide having a molecular weight of approximately 58,000 was detected with all three antisera and with both the double antibody and the protein a-sepharose techniques , while p antiserum also precipitated polypeptides of molecular weights 72,000 , 67,000 and 44,000 , which probably represent the dna binding protein and related polypeptides , respectively .
