ABSTRACT:
A coagulation active complex of Factor VIII fragments is produced by causing a coagulation inactive FVIII heavy chain to react with a coagulation inactive FVIII light chain in the presence of a complex forming agent. Thus, FVIII-HC and FVIII-LC are converted to coagulation active FVIII complex in the presence of metal ions, such as Mn.sup.2+, Ca.sup.2+, or Co.sup.2+ or a component of the prothrombin complex or a substance having reactivity to compounds containing the group --SH and/or --S--S.
