a potent toxin formed and excreted by the bacterial cell and found free in the surrounding medium; exotoxins are the most poisonous substances known. They are protein in nature and heat labile, and are detoxified with retention of antigenicity by treatment with formaldehyde.
Endotoxins are small, stable, bacterially-derived hydrophobic molecules which can easily contaminate labware and whose presence can significantly impact both in vitro and in vivo experiments.2 Their presence is detected by the limulus amebocyte lysate (LAL) assay which can detect down to 0.01 Endotoxin Units (EU)/ml.
