Packaging and Storage The volume of injection in solitary-dose containers gives the amount specified for parenteral administration at a person time and in no case is more than ample to permit the withdrawal and administration of 1 L.

tests. As part of the commitment, we offer the Monocyte Activation Test (MAT) In accordance with EP 2.6.thirty. The MAT is predicated on the human response to pyrogens that induce a fever and may be utilized as an alternative for the rabbit pyrogen test.
The American clinical researcher Fred Bang documented in 1956 that gram-damaging microorganisms, even when killed, will trigger the blood of the horseshoe crab to change into a gel, a kind of semi-stable mass.

Collect aseptically containers that happen to be free of detectable endotoxins in depyrogenated glassware apparatus.
5 ml for every kg and not in excess of 10 ml per kg of body fat. History the temperature of each animal at 50 percent-hourly intervals for three hours after the injection. The difference between the "First temperature" as well as "greatest temperature" that is the highest temperature recorded for the rabbit is taken to generally be its reaction. When this distinction is adverse, The end result is counted to be a zero reaction.
Perform the test utilizing a group of a few rabbits. Preparation of the sample. Dissolve the compound less than assessment in, or dilute with, pyrogen-totally free saline Answer or other Alternative prescribed in the monograph.
