Abstract

In a method of producing a blood-coagulation-promoting preparation based on human proteins and having a content of coagulation factors II, VII, IX and X and factor-VIII-inhibitor-bypassing-activity (FEIBA), human plasma is treated with sulphated high-polymer carbohydrates and/or with basic ion exchangers, the protein mixture with generated FEIB-activity is adsorbed on the ion exchanger, and the preparation is gained by elution and concentration.
