They are really an important mediator of sepsis and septic shock.
Endotoxin release might initiate an immune cascade on host cells, most likely producing a systemic inflammatory reaction.
Standards give a recognised focus of endotoxins for precise calibration and measurement of sample values. Here are a few ideas:
