We co-calibrated the potency of the proposed preparations against the 3rd International Standard （10/178） using the gel-clot method, kinetic-turbidimetric test and kinetic-chromogenic test. A total of 14 laboratories participated in this collaborative study. By comparing precision of three approved candidates＇ calibration results and analyzing the differences among the three results from different methods, we ultimately selected one of candidates as 8th National Standard of Endotoxin, and its potency is 9000 EU/ampoule and lot is 150801-201601.展开更多
