Factor VIII Antibody

Coagulation Factor VIII (FVIII) is an essential blood-clotting protein. By in situ hybridization, Tantravahi et al.(1986) concluded that the F8 gene is located in the proximal part of chromosome Xq28 with probes DX13 and St14 distally located. The F8 gene encodes coagulation Factor VIII, a large plasma glycoprotein that functions in the blood coagulation cascade as a cofactor for the F9a-dependent activation of F10. Factor VIII is activated proteolytically by a variety of coagulation enzymes, including thrombin(F2). It is tightly associated in the blood with VWF, which serves as a protective carrier protein for Factor VIII (Toole et al., 1984; Hoyer, 1994).
