in vivo pyrogen testing. Even though the in vitro pyrogen testing is completed outside the house a living method (i.e. inside of a test plate or card) making use of antigenic substances, the in vivo pyrogen testing is Generally performed inside a residing technique like in a very laboratory mouse or rabbit. The

 Protocols must evaluate the source of endotoxins Utilized in the examine, bearing in your mind that purified bacterial endotoxins may possibly respond in different ways from native resources of endotoxins.
