The inclusion bodies carry lipopolysaccharide with them; it is removed by washing, by ion-exchange chromatography and by specific adsorbents, but removal is never complete and must be verified. Proteins made in mammalian or yeast cells start with far less. The figure on an E. coli-derived protein is a measure of purification quality.
Endotoxin is heat-stable and passes sterilising filters, so it cannot be removed at the end.
Immune cells respond to endotoxin at picograms per millilitre; many other cell types respond at nanograms. A proliferation or signalling assay that attributes a result to IGF-1 receptor agonism when endotoxin is present has a confound. For the biomanufacturing market, where media components enter production of injectable medicines, the limit is also a product-safety requirement.
The specification per microgram of protein, rather than per millilitre, reflects that the reagent is used by mass.
Endotoxin units per microgram or per milligram, by the limulus amebocyte lysate or recombinant factor C assay. For material intended for cell work it is a line to look for.
