FIELD: biotechnology.
SUBSTANCE: described is a composition suitable for treating haemophilia A, containing purified recombinant FVIII, obtained by a method for purifying or enriching the FVIII coagulation factor using chromatography. In one embodiment, the FVIII blood binding factor is obtained by chromatography, comprising the steps of: providing a fraction containing FVIII, bringing the fraction into contact with a cationic multimodal resin, washing the cationic multimodal resin with an aqueous wash buffer and eluting the fractions containing FVIII with an aqueous eluating buffer.
EFFECT: proposed invention extends the range of products for treating haemophilia A.
