Abstract
Antihemophilic factor (AHF), a blood component necessary for clotting of normal whole blood, is extracted from cryoprecipitate containing AHF and fibrinogen as its principal components by: rapidly raising and thereafter lowering the temperature of the cryoprecipitate suspension to selectively denature the fibrinogen in the suspension; and separating the AHF-rich supernatant from the denatured fibrinogen.
