Prothrombin isolated from duck sodium citrate plasma was activated in a system containing duck factor Xa and calcium ions. Polyacrylamide gel electrophoresis showed that intermediates and the final product, thrombin, of Mr in the range 21 500-52 000 were present in the incubation mixture Serine and isoleucine were found to be the N-terminal amino acids of the intermediate form 1 and thrombin, respectively.
从鸭柠檬酸钠血浆中分离出的凝血酶原在含有鸭因子Xa和钙离子的系统中被激活。聚丙烯酰胺凝胶电泳显示，孵育混合物中存在分子量在21500 - 52000范围内的中间体和终产物凝血酶。发现丝氨酸和异亮氨酸分别是中间体形式1和凝血酶的N端氨基酸。
