EtEraser™ SE Endotoxin Removal Kit utilizes food grade modified ε-poly-L-lysine ashigh affinity ligand for endotoxins. The resin is agarose beads which is verystable and has no cytotoxic effect to human body.


Lipopolysaccharide (LPS) is a bacterial endotoxin and a major constituent of the cell walls of gram negative bacteria. Recombinant protein from E.coli usually contains high level of endotoxins. The removal of these endotoxins is highly necessary for downstream processes.

EtEraser SE Endotoxin Removal kit are designed to remove endotoxin contamination from aqueous solutions. The kits contain endotoxin removal resin binds to reduce endotoxin levels in protein samples by ≥ 99 % in less than 2 hours.

The kit includes a pre-packed endotoxin removal column 1.5 ml, Equilibration Buffer, Regeneration Buffer and pyrogen-free collection tube and tips. The column has a high binding capacity of > 2,000,000 EU / ml. This product may be reused up to five times if properly regenerated. The affinity resin is available in slurry and could be up-scalingin biopharmaceutical process.


• high stability — does not affect the activity of most of the biological sample

• high bonding capacity — >2000000 EU/ml

• non-toxic —–> Non-toxic food grade ligands, no cytotoxic effects poly lysine

• high protein recovery — >95% protein recovery for protein samples

• high removal efficiency — remove >99% endotoxin, endotoxin level in the sample can be less than 0.1 EU/ml after endotoxin removing process

• wide application range — can be used in endotoxin removal for proteins, peptides, antibodies, vaccines, polysaccharide and other biological samples


EtEraser SE Endotoxin Removal kit utilizes food grade modified ε-poly-L-lysine as high affinity ligand for endotoxins. The resin is agarose beads which is very stable and has no cytotoxic effect to human body. After purification, there will no toxic residual remained in the samples. This endotoxin removal kit can be used in protein drugs, vaccines, antibodies, DNA/RNA, polysaccharide and other biological samples.
