Lal sensitivity
WebIt is on this basis that LAL has become the sensitive test reagent made from the soluble protein extract (lysate) of horseshoe crab blood cells (amoebocytes). All commercial lysates can detect picograms (10 − 12 g) of endotoxin. The reference test in the pharmacopoeias is the gel clot (or gelation) and is conducted on the end-point principle.
