Demasking is the process of chemically reversing the LER effect prior to testing. This usually requires a combination of: Adding excess Mg2+cap M g raised to the 2 plus power Ca2+cap C a raised to the 2 plus power

To provide a systematic framework for:

: If LER is confirmed, the report suggests strategies such as adding dispersants, using sample demasking reagents (e.g., ENDO-RS), or switching to alternative biological assays like Rabbit Pyrogen Testing for batch release. 4. Document Accessibility

| Area | Action | |------|--------| | | Include LER assessment using spiked samples stored under representative conditions (time, temperature, container). | | Sample Handling | Test within 4 hours of sampling when possible. If delay occurs, justify storage conditions. | | Neutralization | Evaluate alternatives to standard dilution (e.g., high dilution, Mg++ addition, heating) to dissociate complexes. | | Container Evaluation | Screen primary containers (pre-filled syringes, vials) for endotoxin adsorption. | pda technical report 82 pdf

The report provides the statistical justification to present this to the FDA as a robust alternative, provided you have shown the virus log reduction value (LRV) is still >4.0.

Traditional plastics and elastomers used in packaging can become brittle and fracture at ultra-low or cryogenic temperatures. Demasking is the process of chemically reversing the

Explaining how chelators and surfactants dissociate endotoxin aggregates, allowing surfactants to coat individual monomers and "mask" them from detection.
