title: Two independent domains of factor VIII co-expressed using recombinant vaccinia viruses have procoagulant activity.
abstract: Using recombinant DNA technology, the NH2 and COOH terminal domains of the human Factor VIII molecule were co-expressed in baby hamster kidney 21 (BHK21) cells using the vaccinia virus system. Procoagulant activity was detectable in cell supernatants, thus suggesting that the central portion present in the FVIII protein (domain B) is not required for FVIII function.
