Isolation of rat TATA factor as an active 75kDa protein complex

Biochem Biophys Res Commun. 1994 Nov 15;204(3):1125-30. doi: 10.1006/bbrc.1994.2579.

Abstract

A general transcription factor TFIID was purified from rat liver by a sequential column chromatography including organomercurial Sepharose and Sephacryl S-200 chromatographies, which were developed with an acidic buffer (pH5.5). Analyses by SDS-polyacrylamide gel electrophoresis, assay of eluants after renaturation, and immunoblotting showed that isolated TATA factor is an active 75kDa protein complex which contains 36kDa TATA-binding protein.
