FIELD: chemistry.
SUBSTANCE: invention relates to the field of biochemistry, in particular to recombinant factor VIII, which contains one or more mutations, resulting in an increased stability of both the factor VIII and factor VIIIa, as well as to a pharmaceutical composition for treating haemophilia containing it. Also described is a molecule of nucleic acid, coding the said recombinant factor VIII, and an expression vector and host-cells, containing the said molecule of nucleic acid. The invention also relates to a method of obtaining the said factor VIII, as well as to its application in the method of treating haemophilia A in an animal.
EFFECT: invention makes it possible to obtain a biologically active factor VIII with an increased stability.
