During the process of normal blood coagulation prothrombin is converted into thrombin. As a result serum contains considerably less prothrombin than the plasma from which it is derived, the prothrombin having been consumed during the coagulation of the blood. In certain conditions this conversion is incomplete and much prothrombin remains in the serum. Often this is not obvious from the usual t...
We have discovered that addition of monomeric desAB fibrin to prothrombin leads to appearance of the thrombin-like activity of prothrombin towards S2238 chromogenic substrate. DesA and desABβ(15-42)2 fibrin forms did not cause any activation of prothrombin. From this observation we could suggested that amino acid residues of the 15-42 fragment of BβN-domain presented in desAB fibrin, cleaved in...
W ITH increasing use of tests of the prothrombin concentration as an aid in the diagnosis of diseases of the liver and as a guide in vitamin K and dicumarol therapy,’6 it is imperative that the determinations be accurate. There are many ways of measuring the prothrombin concentration and each admits of numerous sources of error. Even when the most careful technic is practiced, appreciable error...
