[five]: the produced level of pNA may be calculated just after a hard and fast incubation period of time. A standard curve, consisting of measured optical density plotted from acknowledged common endotoxin focus.
The endpoint strategy's single measurement usually means it has to be taken at precisely the ideal time for it to triumph or else the test need to be recurring.
The advantage of using the turbidimetric technique around the more simple gel-clot strategy is always that it offers a quantitative consequence, demonstrating the level of endotoxin in the sample Option.
