Citrate, phosphate, and EDTA often accelerate masking.
Guidance on hold-time studies and masking/demasking strategies. ### Understanding Low Endotoxin Recovery (LER) Use "Natural Endotoxin" (NOE) vs
Discussion on the Monocyte Activation Test (MAT) or Recombinant Factor C (rFC) as potential solutions. ### Regulatory Significance
📍 Simply passing a USP validation is no longer enough if your formulation is prone to LER. You must demonstrate recovery over the actual storage duration of the product. ### How to Implement TR 82 in Your Lab
