The amount of endotoxin in protein, peptide or antibody samples is measured by the Limulus Amebocyte Lysate (LAL) test with an endotoxin kit. The concentration of endotoxin in the test specimens is calculated by the LAL kit by chromogenic signal in the presence of endotoxin. This measurement is performed on a microplagin absorption reader at 405 nm. Protein and antibody samples are measured every 30 minutes. The importance of determining the level of endotoxin in evaluating the effectiveness of endotoxin removal methods as well as preventing endotoxic shocks and animals injected with endotoxin-contaminated proteins is very important.

true

An antiendotoxin is any substance which counteracts the effect of an endotoxin.

no it is exotoxin , as its a gram positve baceria

yes
