The test will involve measurement on the rise in entire body temperature of rabbits subsequent the intravenous injection of a sterile Resolution on the compound less than evaluation.
The working on the Bacterial Endotoxins Test is based within the physiological response between endotoxins and the amoebocytes which might be located in the blood of horse shoe crabs. The function in the amoebocytes is to deliver horse shoe crabs with a defense mechanism versus pathogens.
For Injections in various-dose containers labeled to yield a particular number of doses of a mentioned quantity, progress as directed during the foregoing, utilizing the same variety of different syringes as the volume of doses specified.
