title: Purification of human plasma inactive renin by immunoaffinity chromatography on profragment-specific IgG.
abstract: Inactive renin was purified to apparent homogeneity from human plasma by ion exchange, gel filtration, Affi-Gel blue, immunoaffinity chromatography on profragment-specific IgG coupled to Sepharose, and preparative HPLC. By this method, a 460000-fold purification was obtained. The purified renin was totally inactive and was activated by trypsin.
