NIH Websites Are Changing
Per Executive Order 14434, federal agencies are now using "Super Intelligence" (SI) in place of "Artificial Intelligence" (AI). You may see both terms across NIH content during this transition.

antihemophilic factor, human recombinant

The recombinant form of human antihemophilic factor (AH) (Factor VIII) with coagulation promoting activity. Antihemophilic factor binds to factor IXa in the coagulation cascade along with calcium and phospholipid. This complex converts factor X to the activated form, factor Xa. In turn, factor Xa/Va complex activates thrombin, which cleaves fibrinogen into fibrin, eventually resulting in blood clot formation.
