Modified factor VIII cDNA

摘要

A modified Factor VIII cDNA is described in which the B-domain of the wild-type Factor VIII cDNA has been deleted and a truncated Factor IX intron 1 has been inserted in one or more locatons of the Factor VIII cDNA. Such modified Factor VIII cDNA may be used for a higher yield production of Factor VIII in vitro as well as in a transfervector for gene therapy.
