In some bioproducts, residual host cell proteins (HCPs) include enzymes that can cleave or modify the lipid A domain of endotoxin—the portion responsible for LAL activation. This destroys activity but not toxicity. TR 82 notes that modified endotoxin may be undetectable but still bioactive in vivo . The core recommendation of TR 82 is to

PDA Technical Report No. 82 (TR 82), "Low Endotoxin Recovery," provides a standardized, industry-accepted framework for investigating and mitigating the masking of endotoxins in biologics. The 2019 report establishes criteria for hold-time studies, focusing on product-specific impacts and the use of reference standards.
