This active clotting enzyme ends up catalyzing the conversion of procoagulogen right into a device made from the polypeptide, which can be a coagulogen. This subunit then be a part of up via a disulfide bond to kind a gel-clot. This precipitate is then calculated utilizing spectrophotometry to ascertain if there are actually endotoxins within a sample.
