Endotoxin
Test Code: 3046
Clinical Utility
Quantitative determination of endotoxin in environmental samples by the Limulus Amoebocyte Lysate method.
Procedure
Limulus Amoebocyte Lysate method: The activation, from proenzyme to active enzyme, of amoebocytes protein isolated from horseshoe crab, is sensitive to catalysis by bacterial endotoxin. The initial rate of activation is determined by the amount of endotoxin present. The activated enzyme catalyzes the release of strongly colored p-nitroaniline (pNA) from the colorless substrate Ac-Ile-Glu-Aa-pNA, and the rate of release of pNA is monitored photometrically at 405 nm. Activity produced by endotoxin-containing samples is quantified by comparison to standards of known endotoxin concentration. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
