Ph. eur. human thrombin
WebHuman alpha-thrombin, the thromboplastin activation product of prothrombin with high clotting and esterase activity, was produced from Cohn Fraction III paste. The procedure started with 0.4 to 3.2 kg of frozen paste and was completed in 2 or 3 days. Some 23 g of thrombin were recorded for 65 quantitated preparations made from 11 lots of Fraction III … WebA pH-driven DNA nanomachine based on the human α-thrombin binding aptamer was designed for the specific catch-and-release of human α-thrombin at neutral and acidic pH, respectively. In neutral conditions, the thrombin aptamer component of the nanomachine is exposed and exists in the G-quadruplex conformation required to bind to the target …

WebIn the penultimate step of the coagulation cascade, prothrombin is converted to thrombin by the prothrombinase complex composed of factor Xa (F10), cofactor Va (F5), and phospholipids. This activation requires factor Xa-catalyzed sequential cleavage at 2 sites, Arg-314 and Arg-363, along 2 possible pathways. ... uc001ndf.5 human; Similar Proteins. Web7. júl 2009 · The aim of this study was to compare the effect of thrombin (Thr) on cytosolic calcium [Ca 2 ] + i and intracellular pH [pH]i in human and murine platelets. Rich-platelet suspensions from both species were loaded with Fura-2 (2 w M) or BCECF (0.75 w M) by incubation with their respective acetoxymethyl esters to measure cytosolic calcium [Ca 2 ...

Thrombin is produced by the enzymatic cleavage of two sites on prothrombin by activated Factor X (Xa). The activity of factor Xa is greatly enhanced by binding to activated Factor V (Va), termed the prothrombinase complex. Prothrombin is produced in the liver and is co-translationally modified in a vitamin K-dependent reaction that converts 10-12 glutamic acids in the N terminus of the molecule to gamma-carboxyglutamic acid (Gla). In the presence of calcium, the Gla residues pro…
