Ensuring patient safety through reliable bacterial endotoxin testing (BET).
Techniques to "unmask" endotoxins so they become detectable again (e.g., using magnesium, albumin, or specific dispersants). pda technical report 82 pdf
FDA and EMA inspectors frequently cite TR 82 as the "gold standard" for evaluating whether a manufacturer has adequately addressed endotoxin masking. If your product contains polysorbates and a buffer, regulators expect to see an as part of your Biologics License Application (BLA). If your product contains polysorbates and a buffer,
LER occurs when a known amount of endotoxin is added to a drug product but cannot be recovered or detected during testing over time. This is not a failure of the test itself, but rather a where the endotoxin molecules (LPS) are rearranged into structures that the Limulus Amebocyte Lysate (LAL) reagent cannot recognize. Common LER Triggers Common LER Triggers Addressing the "LER" phenomenon where
Addressing the "LER" phenomenon where endotoxins become undetectable.
