The sample suspected to consist of endotoxins is launched into a solution made up of an endogenous substrate. This substrate is cleaved upon introduction with the endotoxin made up of sample generating turbidity. Advancement of turbidity signifies irrespective of whether a sample contains endotoxins or not.
