In an eye-opening discussion at Microbiology Week, Cheryl Platco (Principal Scientist, Microbiology) of Merck & Co. led the group with a session entitled "Low Endotoxin Recovery (LER) - History, Definitions, Testing Strategies and Resolution". Her session covered:

1. The Origins of Low Endotoxin Recovery
2. Low Endotoxin Recovery vs. Low Lipopolysaccharide Recovery (LLR)
3. Designing an LER Study

When designing your own LER study, a protocol is useful outlining the purpose and method of the study, as well as providing a data analysis.
