Novel procoagulant proteins which comprise the amino acid sequence: A-X-B wherein region A represents the polypeptide sequence Ala-20 through Arg-759 substantially as shown in Table 1; region B represents the polypeptide sequence Ser-1709 through Tyr-2351 substantially as shown in Table 1; and region X represents a polypeptide sequence comprising up to 949 amino acids substantially duplicative of sequences of amino acids within the sequence Ser-760 through Arg-1708 of Table 1, wherein the amino terminus of X is covalently bonded through a peptide bond designated "-" to the carboxy terminus of A, and the carboxy terminus of X is likewise bonded to the amino terminus of B. Methods of making such proteins and their use in pharmaceutical preparations is also disclosed. |
