Endotoxins consist of a core polysaccharide chain, O-specific polysaccharide side chains (O-antigen) and a lipid component, Lipid A, which is responsible for the toxic effects (see figure). Endotoxins are approximately 10 kDa in size, but readily form large aggregates up to 1000 kDa.ater is perhaps the greatest source of endotoxin contamination in the laboratory. High purity water is absolutely essential. While distillation and deionizing columns do not remove endotoxin, special columns or filtering systems have been shown to be effective.

Great News! The MDNR director Rebecca Humphries has signed our new Michigan bass season fisheries order during November. We will have a new catch-and-immediate-release bass season in 2006 starting in the entire Lower Peninsula on the last Saturday in April (same as pike and walleye inland). We did not get the longer season on the Great Lakes. The Great Lakes also opens the last Saturday in April in the Lower Peninsula. The Upper Peninsula catch-and-immediate-release bass season starts on May 15 again the same as pike and walleye. What's really great is keep our existing opening days, Memorial weekend for most, and the third Saturday in June for the St. Clair system.
