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. ... The factor VIII gene produces two alternatively spliced transcripts
2. What Is Antihemophilic Factor?
• Antihemophilic factor is a naturally occurring protein in the blood that
helps blood to clot. A lack of antihemophilic factor VIII is the cause of
hemophilia A. Human antihemophilic factor works by temporarily
raising levels of factor VIII in the blood to aid in clotting.

10. A biopharmaceutical is any pharmaceutical drug product manufactured
in, extracted from, or semi-synthesized from biological sources. They
include vaccines, blood components, gene therapies, recombinant
therapeutic protein etc.
FVIII is a glycoprotein procofactor. In the blood, it mainly circulates in a
stable non-covalent complex with von Willebrand factor. It is activated
by thrombin (factor IIa)

12. The availability of recombinant coagulation factors has been a major advance in
the area of hemophilia, providing the promise of improved safety, ease of use,
and reducing the risk of infections transmitted by transfusion.
Hemophilia is caused by the failure to produce certain proteins required for
blood clotting: factor VIII (hemophilia A) or factor IX (hemophilia B).
Because the genes encoding these factors are on the X chromosome, these
diseases (termed "X-linked") usually affect only men, who carry only one X
chromosome. Women carrying the disease gene are "carriers" and can transmit
the disease, mainly to their sons.
13. Recombinant factor VIII is a glycoprotein which is produced by
recombinant DNA technology. It is used for people who have developed
antibodies against replacement coagulation factor.
The gene for factor VIII is located on the X chromosome (Xq28)..
This biomedicine is produced in baby hamster kidney cells (BHK) and
has similar characteristics and functions with the native blood factor
VIII.
14. Clotting Factor VIII Production
Obtaining the molecular clone of a gene can lead to the development of
organisms that produce the protein product of the cloned genes, termed
a recombinant protein.
BHK-21 cells are transfected by human adenovirus D, containing the
F8 gene. The cells are then cultured in fetal bovine serum 5% in large
steel tanks.
Recombinant Clotting Factor VIII (Antihemophilic Factor) is then
obtained by purification of culture.
