Factor VIII (FVIII) is an essential blood-clotting protein, also known as anti-hemophilic factor (AHF). In humans, factor VIII is encoded by the F8 gene. Defects in this gene result in hemophilia A, a recessive X-linked coagulation disorder. Factor VIII is produced in liver sinusoidal cells and endothelial cells outside … See more Factor VIII was first characterized in 1984 by scientists at Genentech. The gene for factor VIII is located on the X chromosome (Xq28). The gene for factor VIII presents an interesting primary structure, as another gene ( See more Factor VIII protein consists of six domains: A1-A2-B-A3-C1-C2, and is homologous to factor V. The A domains are See more FVIII concentrated from donated blood plasma, or alternatively recombinant FVIIa can be given to hemophiliacs to restore hemostasis. Antibody formation … See more In the 1980s, some pharmaceutical companies such as Baxter International and Bayer sparked controversy by continuing to sell contaminated factor VIII after new heat … See more FVIII is a glycoprotein procofactor. Although the primary site of release in humans is ambiguous, it is synthesized and released into … See more Factor VIII related antigen is used as a target for immunohistochemistry, where endothelial cells, megakaryocytes, platelets and mast cells normally stain positive. See more Factor VIII was first discovered in 1937, but it was not until 1979 that its purification by Edward Tuddenham, Frances Rotblat and coworkers led to the molecular identification of the protein.
