Minimal Endotoxin Recovery (LER) is a controversial matter that's been circulating through the endotoxin detection Neighborhood considering the fact that 2013.
These 3 documents explain the elemental ideas from the gel clot, photometric, and kinetic test solutions, and recommend that acceptable factors and concluded merchandise be tested to the presence of pyrogens and endotoxins.
