The LAL test is undoubtedly an enzymatic-situated in vitro test utilizing the horseshoe crab’s blood. The horseshoe crab’s blood consists of a protein named Component C (FC) which interacts with endotoxins. An addition of endotoxin to your blood brings about a response cascade, starting by FC, causing an enzymatic response in which a proclottting enzyme is activated and builds a gel clot.
The test consists of measurement of your increase in overall body temperature of rabbits pursuing the intravenous injection of a sterile Resolution with the compound underneath examination.
