Reveals not just the existence of endotoxin, and also the quantity existing. Success are calculated from a regular curve.
Regardless of their sensitivity and specificity for endotoxins of Gram negative germs, the LAL test is restricted – as it are unable to detect exotoxins of Gram good bacteria and cellular factors of viruses and fungi.
This pyrogen test is similar to your LAL test because it makes use of An analogous Organic system. The large benefit of this process would be that the recombinant Variable C is synthesized rather than making use of the crab’s blood.
