Addressing the "LER" phenomenon where endotoxins become undetectable.
I can provide more detailed technical insights based on your specific formulation needs. Storage conditions can influence the rate of recovery loss
Detailed protocols on how to spike samples and at what intervals to test them to ensure stability.
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
Biopharmaceutical products containing polysorbates and buffers (e.g., citrate or phosphate).
