The conversion of fibrinogen to fibrin: recombinant fibrinogen typifies plasma fibrinogen.
Plasma fibrinogen is a mixture of multiple molecular forms arising mainly through alternative mRNA processing and subsequent posttranslational modification. Recombinant fibrinogen is synthesized without alternative mRNA processing in a cultured cell system that may generate novel posttranslational modifications. Thus, to show that recombinant fibrinogen can serve as a functional model for plasm...
متن کاملThe Conversion of Fibrinogen to Fibrin
1. Fibrin clots prepared in the absence of calcium can be dissolved in solutions of lithium chloride and bromide and sodium bromide and iodide, as well as of guanidine hydrochloride and urea. These salts do not denature fibrinogen under the same conditions of concentration, temperature, and time. Sedimentation experiments on the fibrin solutions show in each case a single sharp peak with a sedi...
متن کاملSignificance of Cryoprofibrin in Fibrinogen-fibrin Conversion
Fibrinogen altered by thrombin-catalyzed liberation of fibrinopeptide A was found to combine with native fibrinogen to form a cold-precipitable complex we have called "cryoprofibrin." The altered fibrinogen lacking fibrino-peptide A polymerized into fibrin, but not until conditions for equilibrium between its incorporation into both cryoprofibrin and fibrin were satisfied. At equilibrium, the c...
متن کاملFibrinogen-fibrin degradation products.
The identification of the molecular structure of fibrinogen has given a better understanding of many clinical conditions associated with abnormalities of fibrinogen. Proteolysis of fibrinogen or fibrin by its natural lytic enzyme, plasmin, leads to the formation of degradation products which are of great importance in the laboratory diagnosis of many pathological conditions. The biochemical and...
متن کاملStudies of platelet fibrinogen from a subject with a congenital plasma fibrinogen abnormality (fibrinogen Paris I).
Fibrinogen from normal platelets and plasma was compared with material derived from a subject with the congenital fibrinogen abnormality termed fibrinogen Paris I. The molecular abnormality in this subject is characterized by the presence (in plasma molecules) of relatively large mutant ‘y-chains (‘y-Paris I) that replace 50% or more of the normal “y-chain population and that, unlike normal ‘y-...
