Description and Specification


Description Detoxi-Gel Endotoxin Removing Gel
Formulation Polymixin B on crosslinked 6% beaded agarose slurried in 25% ethyl alcohol
Quantity 10mL
Sufficient For Binding approx. 10,000 endotoxin units of LPS per mL of resin per use
Support Type Agarose

Detoxi-Gel Resin is a beaded agarose support onto which polymixin B has been immobilized. This ligand binds to the lipid A portion of lipopolysaccharides (LPS), which are the dominant form of endotoxins that affect biological samples. Even low levels of endotoxins can be toxic to cells or organisms and must be removed before biological samples can be added to cells for various treatment experiments. Detoxi-Gel Resin provides a quick method for removal of endotoxins from samples. It is available in convenient pre-packed columns and two sizes of slurry for use in small-scale or large-scale processes.


  • Affinity-based – uses immobilized polymixin B to remove endotoxins by binding to their lipid A domains

  • High capacity – 1mL of Detoxi-Gel Resin removes at least 9995 endotoxin units from a 5mL sample containing 10,000 EU of lipopolysaccharide (LPS)

  • Reusable – no loss in binding capacity even after 10 regenerations; requires activation and regeneration with 1% sodium deoxycholate (Part No. 89904)

  • Testing required – protein recovery is dependent upon protein type and concentration; empirical testing is required to validate the method for particular protein samples

  • Versatile – remove endotoxin from protein solutions, cell culture media and pharmacological components


Sodium deoxycholate (Part No. 89904) for resin activation and regeneration.
