Pierce™ High Capacity Endotoxin Removal Resin (Thermo Scientific™)

Thermo Scientific Pierce High Capacity Endotoxin Removal Resin binds to reduce endotoxin levels in protein samples by ≥99% in 1 hour while maximizing protein recovery. Use this endotoxin removal resin slurry to pack a custom column that can be re-used up to 10 times with no loss in endotoxin removal efficiency.

Features of High Capacity Endotoxin Removal Resin:

• High capacity—bind up to 2,000,000 EU/mL^† to eliminate >99% of endotoxins
• Durable—re-use resin up to 10 times with no loss in performance
• Selective—recover ≥85% of your protein sample
• High performance—meets FDA guidelines by reducing final EU concentration to <5 EU/mL
• Economical—large-volume discounts available

The Pierce High Capacity Endotoxin Removal Resin combines porous cellulose beads and an FDA-approved food preservative, poly(ε-lysine), as an affinity ligand to selectively bind endotoxins. Endotoxin levels in protein samples are reduced by ≥99% in as little as 1 hour using our spin cup format, and protein recovery is ≥85%. The modified polylysine affinity ligand eliminates the toxicity concerns associated with alternative technologies using polymixin B ligands and sodium deoxycholate buffers.

Requires:
Endotoxin-free water
Applications:

Eliminate endotoxins from protein or antibody samples prior to cell transfection or animal injection

The presence of endotoxins in biologically derived products prepared for research, vaccination, or therapeutic use is a major concern due to the diverse and potentially harmful biological response to these molecules. Endotoxin contamination in proteins purified from bacterial cultures is due to residual lipopolysaccharides (LPS) derived from the outer cell membrane of gram-negative bacteria such as E. coli. Endotoxin-contaminated protein samples transfected into cells or injected into an animal host can initiate a strong immune response resulting in a Systemic Inflammatory Response Syndrome (SIRS) and/or sepsis. Traditional endotoxin removal resins that use polymixin B and sodium deoxycholate to clear endotoxins from a sample also have the negative side effects of neurotoxicity and acute renal tubular necrosis.

Pierce High Capacity Endotoxin Removal Resin is a porous cellulose bead that has been surface-modified with covalently attached polylysine chains that have a high affinity for LPS but lacks the toxicity of other endotoxin-binding molecules. With a 2,000,000-EU/mL binding capacity, endotoxin levels can be reduced by 99% in samples containing initial endotoxin levels of 10,000 EU/mL. Typical protein samples processed with the High Capacity Endotoxin Removal Resin have a final endotoxin concentration below 5 EU/mL. This resin is offered in a slurry format for custom packing of endotoxin removal columns for gravity flow or flow rates ranging from 10-15 mL/hour.

^† One endotoxin unit/mL (EU/mL) equals approximately 0.1ng endotoxin/mL of solution.
