Wow interesting, thank you. Bt Delta Endotoxin https://en.wikipedia.org/wiki/Lipopolysaccharide#Health_effects https://en.wikipedia.org/wiki/Lipopolysaccharide#Health_effe... an interesting side note, endotoxin test have relied on availability of horseshoe crab blood: The standard assay for detecting presence of endotoxin is the Limulus Amebocyte Lysate (LAL) assay, utilizing blood from the Horseshoe crab (Limulus polyphemus).[44] Very low levels of LPS can cause coagulation of the limulus lysate due to a powerful amplification through an enzymatic cascade. However, due to the dwindling population of horseshoe crabs, and the fact that there are factors that interfere with the LAL assay, efforts have been made to develop alternative assays, with the most promising ones being ELISA tests using a recombinant version of a protein in the LAL assay, Factor C.[
