It sounds like you’re looking for a specific feature, table, figure, or section from PDA Technical Report No. 82 (TR-82), titled “Low Endotoxin Recovery” (published 2020).

Final Action Items:

• The coldest points in the system (lowest points, dead legs).
• The return loop.
• Distal points furthest from the heat source.
• Acceptance Criteria: All monitoring points must demonstrate that the minimum required temperature is achieved and held for the specified duration.

PDA Technical Report No. 82 (TR 82), titled "Low Endotoxin Recovery," was published in March 2019 to provide critical guidance on the phenomenon of Low Endotoxin Recovery (LER). pda technical report 82

1. A specific figure or table (e.g., "Figure 3.1 showing LER timeline" or "Table of root causes")
2. A key procedural feature (e.g., "dilution neutralization step," "use of rFC vs. LAL," "sample handling time limits")
3. A feature of the LER phenomenon (e.g., "masking vs. binding," "recovery vs. time profile")
4. A feature of the recommended control strategy (e.g., "routine spiking," "sample storage conditions")

LER is defined as the inability to recover $\geq$50% activity over time when a known amount of endotoxin is added to an undiluted product. It is particularly common in biologics containing a combination of chelators (like citrate or phosphate) and surfactants (like polysorbate).
