The first recombinant human coagulation factor VIII of human origin: human cell line and manufacturing characteristics

The first recombinant human coagulation factor VIII of human origin: human cell line and manufacturing characteristics

INTRODUCTION Since the early 1990s, recombinant human clotting factor VIII (rhFVIII) produced in hamster cells has been available for haemophilia A treatment. However, the post-translational modifications of these proteins are not identical to those of native human FVIII, which may lead to immunogenic reactions and the development of inhibitors against rhFVIII. For the first time, rhFVIII produ...

Human coagulation factor VIII domain-specific recombinant polypeptide expression

BACKGROUND Hemophilia A is caused by heterogeneous mutations in F8. Coagulation factor VIII (FVIII), the product of F8, is composed of multiple domains designated A1-A2-B-A3-C1-C2. FVIII is known to interact with diverse proteins, and this characteristic may be important for hemostasis. However, little is known about domain-specific functions or their specific binding partners. METHODS To det...

Development of aptameric affinity ligands specific to human plasma coagulation factor VIII using SEC-SELEX

Protein specific aptamers are highly applicable affinity ligands in different fields of research and clinical applications. They have been developed against various targets, in particular, bio-macromolecules such as proteins. Among human proteins, the coagulation factors are the most attractive targets for aptamer selection and their specific aptamers had valuable characteristics in therapeutic...
