[Effect of basic plasma polypeptides on the process of blood coagulation and fibrinolysis]. 1993

R A Koldaev, and B I Kuznik, and V Kh Khavinson

An original method was used to isolate polypeptides from citrate platelet-free plasma of healthy subjects. These polypeptides were able to prolong recalcification, kaolin, kaolin-cephalin and prothrombin plasma time, sharply reduce thrombin time of standard and heparinized plasma, to inhibit fibrin self-building and stimulate fibrinolytic activity of blood. An antiheparin effect of polypeptides in adequate doses is similar to that of protamine sulfate. Polypeptide antiheparin plasma factor has molecular mass about 2000 D, its chromatographic profile coincides with that of protamine sulfate.

UI MeSH Term Description Entries
D010455 Peptides Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS. Peptide,Polypeptide,Polypeptides
