mutants of the factor vii activating protease and detection techniques with specific antibodies

摘要

A mutant DNA sequence codes activating protease (FSAP) for the blood coagulation factor VII and in-chain-plasminogen activators. The mutation conmprises a G/A nucleotide base exchange at position 1177 and/or a G/C nucleotide base exchange nucleotide position 1601 of the 1683 nucleotide sequence (SEQ ID 1) defined in the specification. A mutant DNA sequence codes activating protease (FSAP) for the blood coagulation factor VII and in-chain-plasminogen activators. The mutation conmprises a G/A nucleotide base exchange at position 1177 and/or a G/C nucleotide base exchange nucleotide position 1601 of the 1683 nucleotide sequence (SEQ ID 1) defined in the specification. The protease has a Glu/Gln exchange at the amino acid position 393 and/or a Gly/Glu exchange at amino-acid position 534 of the 560 amino acid sequence (SEQ ID 3) defined in the specification. Independent claims are also included for: (1) a diagnostic process to demonstrate the presence of FSAP body fluids or tissue samples to identify patients with genetically determined hetero or homozygote expressions in FSAP; and (2) FSAP antibodies and their mutants and diagnostic processes using the antibodies.
