Endotoxins in laboratory materials
Endotoxins are lipopolysaccharide (LPS) molecules found in the outer membrane of certain bacteria. They can be released when those bacteria break down.
In laboratory materials, endotoxins are an impurity that researchers may wish to keep low depending on the model being studied.
The Limulus Amebocyte Lysate (LAL) assay is the standard bacterial endotoxin test (BET) used to measure endotoxin levels against defined acceptance limits.
Where a lot's Certificate of Analysis includes endotoxin data, it is presented alongside the identity and purity figures.
