| 麻煩問下各位大哥,胰蛋白酶:測(cè)定時(shí)候需要用到USP單位,比如:41.4 Ph.Eur.U/mg 到底表示多少呢?是41.4個(gè)USP單位嗎?麻煩問下,歐洲藥典單位和美國藥典USP單位,之間的換算關(guān)系是什么呢?謝謝了。 |

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. References: 1. Associates of Cape Cod, Inc. LAL Update, Vol. 15, No. 4, December 1997. 2. 2. Poole, S., Dawson, P., and Gaines Das, R.E. 1997. Second international standard for endotoxin: calibration in an international collaborative study. Journal of Endotoxin Research 4(3):221-231. |
