[交流] 【求助】麻烦问一下各位,欧洲药典单位和美国药典单位的区别? 已有2人参与

麻烦问下各位大哥,胰蛋白酶:测定时候需要用到USP单位,比如:41.4 Ph.Eur.U/mg 到底表示多少呢?是41.4个USP单位吗?麻烦问下,欧洲药典单位和美国药典USP单位,之间的换算关系是什么呢?谢谢了。

The conversion of results of an LAL test expressed in EU/ml into IU/ml is very easy: 1 EU=1 IU. The United States Pharmacopoeia, the World Health Organization and the European Pharmacopoeia have adopted a common standard. Various names and lot numbers have been given to this standard (e.g. lot G, EC-6), but the content of the vials is identical and the units are equivalent. This standard consists of endotoxin extracted from the cells of Escherichia coli O113; it is assigned an activity of 10,000 EU or 10,000 IU per vial. Therefore, results in EU can equally be reported in IU and vice versa.
