title: Purification of SV40 T-antigen by SV40 DNA-sepharose affinity chromatography.
abstract: T-antigen from SV40-infected BSC-1 cells was purified approximately 30,000 fold using a rapid purification procedure consisting of ammonium sulfate fractionation followed by chromatography on hydroxylapatite, blue-sepharose, and SV40 DNA-sepharose. The SV40 DNA-sepharose was optimized for the binding of T-antigen by the covalent attachment of the SV40 DNA at its BamHI site to cyanogen bromide activated sepharose. The most highly purified T-antigen appeared as a single polypeptide of 94 K daltons by polyacrylamide gel electrophoresis.
