Protein Endotoxin Removal Kit, also known as protein sample endotoxin removal kit or Protein Endotoxin Removal Kit, is a kit that can efficiently remove more than 99% of the endotoxin in protein solution samples within 15 minutes. Protein samples with an initial endotoxin concentration of 100EU/ml can be treated with this kit with endotoxin levels below 0.1EU/ml to a level considered free of endotoxin contamination. Therefore, this kit is widely used in endotoxin treatment of samples involving cell or animal experiments.
