title: The isolation of prothrombin, Factor IX and Factor X from human Factor IX concentrates.
abstract: A relatively simple and reproducible procedure is described for the isolation of functionally and electrophoretically homogeneous prothrombin, factor IX and factor X from clinical Factor IX Concentrates. The procedure involves ammonium sulphate fractionation; then chromatography on DEAE-Sephadex A50, dextran sulphate-Sepharose and heparin-Sepharose. High recovery of all three procoagulants was obtained: 32% for factor IX; 32% for factor X; 29% for prothrombin.
