What endotoxin level should be expected when purchasing Aladdin proteins? 
For Aladdin’s Animal-Free proteins, the endotoxin level is guaranteed to be less than 0.01 ng/μg of protein, or 0.1 EU/μg. For most of Aladdin’s non-Animal-Free proteins the endotoxin level is guaranteed to be less than 0.1 ng/μg of protein, or 1 EU/μg. However, for many proteins, the actual measured endotoxin values are consistently below these stated endotoxin levels.
