The phenomenon of LER was originally described during the therapeutic items of monoclonal antibodies in April 2013, plus the FDA has thought of LER to get a possible safety issue owing to your probability of Bogus-detrimental test final results.

On one June 2020, The us Pharmacopeia (USP) decided to terminate the proposal to include recombinant technological know-how for endotoxin testing in chapter 85, Bacterial Endotoxins, and begin the development of a independent chapter that expands over the use, validation, and comparability of endotoxin tests determined by recombinantly derived reagents.
