[Determination of fibrinogen concentration in blood plasma by the sulfite precipitation method]. 1979

Two methods using thrombine and sulfite were compared for estimation of fibrinogen concentration in blood plasma. Both methods produced the same results in estimation of fibrinogen in donor blood plasma. If blood plasma contained high amount of products of fibrinogen and/or fibrin degradation, the efficiency of thrombin method was decreased; on the other hand, final concentration of sulfite did not precipitate fragment D of fibrinogen from human blood plasma. Presence of heparin did not influence on the sulfite method but the polysaccharide might interfere in the thrombin method. Some experiments require to use both these methods for evaluation of fibrinogen in blood plasma.

D008722 Methods A series of steps taken in order to conduct research. Techniques,Methodological Studies,Methodological Study,Procedures,Studies, Methodological,Study, Methodological,Method,Procedure,Technique
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.
