[Study of fibrinogen-fibrin cryocomplexes by a quantitative analysis of N-terminal amino acids]. 1983

E V Lugovskoĭ, and G K Gogolinskaia, and S G Derzskaia

The reaction between fibrinogen (F) and thrombin (0.003 NIH/ml) has been investigated under physiological conditions. The action of thrombin was inhibited in various time intervals including gel point (4 h), and the reaction mixtures were allowed to stand 0 degrees C. The F-to-des-AA-fibrin (f) ratios were determined both in the initial reaction mixtures and in corresponding cryoprecipitants by the method of N-terminal amino acids quantitative analysis. It is found that the F/f ratio in the cryoprecipitant depends on the F/f ratio in the initial mixture at 37 degrees C. The F/f = 1 ratio in cryoprecipitant previously found by Shainoff and Page is valid only for the initial F/f = 7 ratio. But the F/f value in cryoprecipitants varies in favour of F or f components, if the F/f ratio increases or decreases in the initial mixture at 37 degrees C, respectively. A possible mechanism of various fibrinogen-fibrin cryocomplexes formation is discussed.

D003080 Cold Temperature An absence of warmth or heat or a temperature notably below an accustomed norm. Cold,Cold Temperatures,Temperature, Cold,Temperatures, Cold
D005337 Fibrin A protein derived from FIBRINOGEN in the presence of THROMBIN, which forms part of the blood clot. Antithrombin I
D005340 Fibrinogen Plasma glycoprotein clotted by thrombin, composed of a dimer of three non-identical pairs of polypeptide chains (alpha, beta, gamma) held together by disulfide bonds. Fibrinogen clotting is a sol-gel change involving complex molecular arrangements: whereas fibrinogen is cleaved by thrombin to form polypeptides A and B, the proteolytic action of other enzymes yields different fibrinogen degradation products. Coagulation Factor I,Factor I,Blood Coagulation Factor I,gamma-Fibrinogen,Factor I, Coagulation,gamma Fibrinogen
D005971 Glutamates Derivatives of GLUTAMIC ACID. Included under this heading are a broad variety of acid forms, salts, esters, and amides that contain the 2-aminopentanedioic acid structure. Glutamic Acid Derivatives,Glutamic Acids,Glutaminic Acids
D005998 Glycine A non-essential amino acid. It is found primarily in gelatin and silk fibroin and used therapeutically as a nutrient. It is also a fast inhibitory neurotransmitter.
