Obtain aseptically containers which can be free of detectable endotoxins in depyrogenated glassware equipment.
The amoebocytes comprise pro-coagulant enzymes that induce a series of reactions; and the final solution of those chain reactions is a gel comprised of here coagulated proteins. The enzymatic response is made if the amoebocytes enter into connection with the endotoxins.
