METHOD OF PRODUCING FIBRINOGEN USING STRONG ANION EXCHANGE RESIN AND FIBRINOGEN-CONTAINING PRODUCT Russian patent published in 2016 - IPC C07K14/75 C07K1/18 A61K38/36 A61P7/04 

FIELD: biotechnology.

SUBSTANCE: group of inventions relates to biotechnology. Invention discloses a method of purifying fibrinogen, a fibrinogen-containing product and use of an anion-exchange resin, containing a hydroxylated methacrylic polymer with trimethylamino groups grafted through binding group, for producing said product using said method. Fibrinogen-containing source undergoes chromatography on anion-exchange resin based on hydroxylated methacrylate polymer with trimethylamino groups grafted through binding group. Fibrinogen-containing product is obtained, having high degree of purity without content of viruses and prions with content of fibronectin of 0.01-1.00 mcg/mg of fibrinogen, fibrinopeptide A 0.01-9.0 ng/mg of fibrinogen, with activity vWF: Ag less than 0.1 IU/mg of fibrinogen, with activity of factor XIII 0.07-1.0 IU/mg of fibrinogen and thrombin activity less than 0.007 IU/mg of fibrinogen.

EFFECT: invention discloses a method of purifying fibrinogen, a fibrinogen-containing product and use of an anion-exchange resin, containing a hydroxylated methacrylic polymer with trimethylamino groups grafted through binding group, for producing said product using said method.
