Proteolytic processing of human coagulation factor IX by plasmin.
Previous studies have shown that thrombin generation in vivo caused a 92% decrease in factor IX (F.IX) activity and the appearance of a cleavage product after immunoblotting that comigrated with activated F.IX (F.IXa). Under these conditions, the fibrinolytic system was clearly activated, suggesting plasmin may have altered F.IX. Thus, the effect(s) of plasmin on human F.IX was determined in vi...
متن کاملCSL Behring Coagulation Factor IX ( Human ) Mononine ® Monoclonal Antibody Purified
only DESCRIPTION Coagulation Factor IX (Human), Mononine, is a sterile, stable, lyophilized concentrate of Factor IX prepared from pooled human plasma and is intended for use in therapy of Factor IX deficiency, known as Hemophilia B or Christmas disease. Mononine is purified of extraneous plasma-derived proteins, including Factors II, VII and X, by use of immunoaffinity chromatography. A murine...
متن کاملPurification and Characterization of Human Coagulation Factor
We have purified human coagulation Factor V 6,000fold to homogeneity from citrated plasma using polyethylene glycol 6000 precipitation, adsorption of Factor V to barium citrate, DEAE-Sepharose chromatography, and gel filtration on Ultrogel AcA 34 (yield 21%). Human Factor V is a single polypeptide chain before and after disulfide bond reduction with an apparent M, = 335,000 as determined by ele...
متن کاملCoagulation Factor IX for Hemophilia B Therapy
Factor IX is a zymogen enzyme of the blood coagulation cascade. Inherited absence or deficit of the IX functional factor causes bleeding disorder hemophilia B, which requires constant protein replacement therapy. Reviewed herein are the current state in the manufacturing of FIX, improved variants of the recombinant protein for therapy, transgenic organisms for obtaining FIX, and the advances in...
متن کاملStructural and functional basis of the developmental regulation of human coagulation factor IX gene: factor IX Leyden.
Hemophilia B Leyden is characterized by unusual developmental regulation of factor IX synthesis in affected individuals. One family affected with the hemophilia B Leyden phenotype was found to have a specific single-base mutation (G----A) at nucleotide -6 of the factor IX gene. The mutation site was found in a small region of the 5'-untranslated sequence designated the Leyden-specific region (L...
