Abstract: Antibodies are provided which are directed against a sequence of amino acids corresponding to amino acids from the sequence 311-379 in particular 311-336 of the .gamma.-chain of fibrinogen. These novel antibodies react specifically with fibrin, both type I and type II. They are effective in detecting, preventing and treating blood clot formation.

Abstract: It is found that blood clotting-factor products previously subjected to monoclonal purification or solvent-detergent treatment or both may be further subjected to a sequence of heating steps without excessive loss of usable product to reduce the infectivity of a virus (such as hepatitis- or AIDS-causing virus), if present. The heating is performed while the concentrate is lyophilized (freeze dried). The heating steps in the sequence are for two or more different times, and at two or more different temperatures. After the heating sequence, the concentrate is reconstituted for use. This sequential method contemplates greater inactivation of different viral forms, or reduction of the heating required, or both. Reduction of heating requirements may appear as reduced overall heating time, or reduced aggregate power consumption, or both. Advantages include heightened quality-control assurance level.

Abstract: Factor VIII analog which has undergone deletion of amino acids 771 to 1666, prepared from eukaryotic cells transformed by an expression vector carrying the cDNA of the factor VIII which has undergone deletion.

Abstract: Factor VIII concentrate, or Factor IX concentrate, or fibrinogen concentrate, or other clotting-factor product, is subjected to a sequence of heating steps to reduce the infectivity of a virus (such as hepatitis- or AIDS-causing virus), if present. The heating is performed while the concentrate is lyophilized (or dried by another process). The heating steps in the sequence are for two or more different times, and at two or more different temperatures. After the heating sequence, the concentrate is reconstituted for use. This sequential method contemplates greater inactivation of different viral forms, or reduction of the heating required, or both. Reduction of heating requirements may appear as reduced overall heating time, or reduced aggregate power consumption, or both. Advantages include heightened quality-control assurance level. Also possibly, the invention offers some potential for preparation of vaccines against the virus, if sufficient quantity of the virus is present in the concentrate.
