The measurement consequence can be utilized to judge the diploma of contamination from the drugs and to evaluate the sanitary good quality of the medication.
The development of such new methods will substantially reduce animal testing. The commercially most thriving substitute process, which replaces the rabbit pyrogen test for bacterial impurities in medicines having a test using human cells, could conserve the lifetime of two hundred,000 rabbits a calendar year.
A h2o activity underneath 0.6 isn't going to empower micro-organisms to increase.
