PDA Technical Report No. 82 (TR 82), "Low Endotoxin Recovery," provides comprehensive guidance for identifying and mitigating the masking of endotoxins in biological products, defining LER as the inability to recover at least 50% of spiked endotoxin. The report outlines specific methodologies for conducting hold-time studies and suggests demasking strategies, such as sample pre-treatment and alternative testing methods like rFC or MAT.

A significant drop in recovery (>50% loss) without corresponding loss in activity signals LER potential. pda technical report 82 pdf
- Clogging: High cell densities and cellular debris rapidly clog standard filters.
- Sensitivity: Cells are living organisms; they cannot tolerate the high pressures or long processing times of standard sterile filtration.
- Product Loss: Forcing a sensitive protein or cell broth through a tight filter can lead to shearing, aggregation, and significant yield loss.
The report explains that LER is a time- and temperature-dependent phenomenon. PDA Technical Report No
