    摘要: A process of manufacturing a prion-free Vitamin K dependent Protein in a purification sequence employing chromatography characterized in that at least one chromatography step is performed using a multimodal resin providing a fraction containing Vitamin K dependent Protein in an aqueous solution; contacting the fraction containing the Vitamin K dependent Protein with a multimodal resin at a pH between 6-9; optionally washing the multimodal resin having the Vitamin K dependent Protein adsorbed with an aqueous washing buffer to wash away contaminants and retain the Vitamin K dependent Protein, before the Vitamin K dependent Protein is eluted; the Vitamin K dependent Protein is eluting from the multimodal resin at a pH between 6 to 9 in a buffer comprising arginine; and optionally collecting Vitamin K dependent Protein containing fractions in purified or enriched form.

    摘要: A method for reduction of the viral infectiousness of potentially infectious material, such as human or animal body fluids or fractions derived therefrom from which biologically active substances can be isolated, wherein the infectiousness is due to non-lipid-coated viruses characterized in thatsaid potentially infectious material for the isolation of said biologically active substances is treated witha hydrophobic phase which is essentially insoluble in water and is capable of forming a two-phase system with said potentially infectious material, andsaid hydrophobic phase is separated from the potentially infectious material thus treated.

    摘要: Described is an economical process for the recovery of factor VIII from blood plasma or cryoprecipitate. In the process, anion exchanger chromatography is conducted using a separating material based on carriers containing hydroxyl groups, the surfaces of which carriers have been coated with covalently boded polymers. The polymers contain repeating units represented by formula (I). ##STR1##
