Determine one. Chromogenic test kit for detection of bacterial endotoxin. LAL test reagent incorporates synthetic chromogenic substrate and buffered amoebocyte lysate of any with the species of a crab stabilized by monovalent and divalent cations. The powdered reagent is reconstituted with buffer ahead of use. Parenteral products and solutions really should be tested for the presence of endotoxins so as to shield their end users from adverse reactions (sepsis).
