METHOD OF PRODUCING FACTOR VIII PROTEINS BY RECOMBINANT METHODS

摘要

Provided herein are methods and compositions for producing Factor VIII proteins. Such methods include introducing into a cell a nucleic acid molecule encoding a Factor VIII protein operably linked to a promoter, wherein the promoter is characterized by the ability to produce commercially viable Factor VIII protein; and incubating the cell under conditions for producing commercially viable Factor VIII protein. Also provided are nucleic acid molecules which encode a Factor VIII protein operably linked to a Chinese hamster elongation factor 1-alpha (CHEF1) promoter, which may be used in the methods provided herein.
