title: Purification of human plasma fibrinogen by chromatography on protamine-agarose.
abstract: A study was performed to investigate if protamine covalently attached to CNBr-activated agarose is a useful tool for the purification of fibrinogen from human plasma samples. One chromatography step yielded a preparation with a clottability greater than 90% from platelet-poor plasma with a yield of 65-80% of fibrinogen applied. The preparation is free of plasminogen, immunoglobulins, fibronectin, albumin, antithrombin III, alpha 2-macroglobulin, and alpha 1-antitrypsin, as determined by immunological and functional methods. 6.5 mg of fibrinogen were adsorbed to 1.0 ml of protamine-agarose. Protamine-agarose chromatography can be applied to plasma samples as small as 200 microliters.
