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, also known as lipopolysaccharides or LPS, are cell membrane components of Gram-negative bacteria (e.g., E. coli).The lipid portion of the outer layer of the outer membrane is completely composed of endotoxin molecules (see figure Schematic diagram of the envelope of E. coli).easuring endotoxins Historically, endotoxins were measured in a clotting reaction between the endotoxin and a clottable protein in the amoebocytes of Limulus polyphemus, the horseshoe crab.
