Endotoxin Removal Solution Catalog Number E4274Product DescriptionEndotoxins are lipopolysaccharides (LPS), a major component of the Gram-negative bacterial cell wall, and are commonly found as contaminants in plasmid DNA preparations from E. coli. Endotoxins are large, negatively charged molecules that co-purify with DNA on ion exchange and size exclusion columns and in CsCl banding. Endotoxins are extremely potent stimulators of the mammalian immune system and are toxic to primary cells and to animals. The endotoxin toxicity is an obstacle to in vitro and in vivo transfection experiments.Non-ionic detergents, traditionally used for separation of integral membrane proteins,1 can be utilized for removal of endotoxins from DNA solutions by phase separation.2The solubility behavior of a detergent in a dilute, aqueous solution at physiological salt and pH conditions is strongly dependent upon the temperature of the solution. At low temperatures, the detergent forms a clear, micellar solution, but above the cloud point temperature, the micelles form larger, turbid aggregates and ultimately fuse to form a separate phase. The lower phase is detergent-enriched and the detergent-depleted upper phase contains detergent at a concentration slightly above the critical micellar concentration (CMC). Amphiphilic and hydrophobic molecules associated with the micelles of the detergent will aggregate within the detergent-enriched phase, while the soluble, hydrophilic molecules will remain in the detergent-depleted upper phase.Extraction of endotoxin contaminated DNA solutions with the appropriate non-ionic detergent will separate the hydrophilic DNA from the amphiphilic endotoxin. The amphiphilic endotoxin will associate with the lower phase, while the DNA will remain in the upper, detergent-depleted phase.2Reagents and equipment required, but not provided • Water, Molecular Biology Reagent, Catalog Number W4502• E-TOXATE® Water, Catalog Number 2107, or Tris-EDTA (TE) buffer 100×, Catalog NumberT9285• DNA solution (0.5 ml), ~ 1 mg/ml in E-TOXATE®Water or TE buffer• 3 M sodium acetate solution, pH 7.5.• 2-Propanol, Catalog Number I9516, or Ethanol, 190 proof, Catalog Number E7148; 200 proof, CatalogNumber E7023• 70% Ethanol• E-TOXATE®reagents Kits, Catalog Numbers 210A1, 210B1 or 210C1• Ice bucket• Heat block or incubator at 37 °C• Microcentrifuge at room temperature• 1.5 or 2 ml sterile microcentrifuge tubes• Endotoxin-free pipet tips (40-200 µl, 200-1000 µl) Precautions and DisclaimerThis product is for R&D use only, not for drug, household, or other uses. Please consult the Material Safety Data Sheet for information regarding hazards and safe handling practices.StorageStore at room temperature.Note: Removal of endotoxins from DNA preparations can be performed either during the final stage of DNApreparation, or during an earlier stage.Procedures for Endotoxin RemovalDuring the final stage of DNA preparationNote: The procedure described below was performed on plasmid DNA produced in E. coli DH5α cells.• Losses of up to 50% of the DNA are expected. • Use of a DNA concentration above therecommended 1 mg/ml reduces the efficiency ofthe procedure.1. Pipette 500 µl of the DNA solution into a sterilemicrocentrifuge tube.2. Add 50 µl of the 3 M sodium acetate solution to theDNA sample.3. Incubate on ice for 5 minutes.4. Add 100 µl of cold Endotoxin Removal Solution.5. Mix thoroughly and incubate on ice for 10 minutes.The solution should be light blue and clear.6. Incubate the tube at 37 °C for 20 to 30 minutes oruntil the phases separate.7. Spin for 5 minutes at 3000 x g in themicrocentrifuge. The upper phase is colorless and clear, while the lower phase is blue.8. Carefully transfer the upper phase containing theDNA to a clean microcentrifuge tube.9. Repeat steps 4 through 8 twice.10. Add 0.6× volume of 2-propanol. Mix by inversion atroom temperature and centrifuge at 15,000 x g for30 minutes at 4 °C. Alternatively, add2.5× volumes of ethanol. Incubate overnight at –20°C or 20 minutes at –70 °C and centrifuge at15,000 x g for 30 minutes at 4 °C.11. Carefully remove the supernatant12. Wash the DNA pellet twice with cold 70% ethanol.Remove the supernatant.13. Air-dry the pellet.14. Suspend the DNA in 100 µl of endotoxin free wateror TE buffer.15. Determine DNA concentration and endotoxin levelsusing endotoxin assay reagents and compare tothe starting material. During an earlier stage of DNA preparationThis procedure is based on the alkaline lysis of E. coli DH5α cells.3 The endotoxins are removed immediately after alkaline cell lysis, neutralization, and a clarification step. The resulting high salt solution is suitable for the endotoxin removal step. It is performed under “endotoxin free” conditions. The plasticware used is either sterile and disposable, or NaOH-treated. The buffers are prepared with endotoxin free water.1. Add the Endotoxin Removal Solution (0.2× volume)to the cold, crude DNA solution.2. Incubate on ice and mix occasionally by inversionto obtain a homogenous, clear blue solution3. Incubate at 37 °C for 20 to 30 minutes until thephase separation is obvious.4. Spin for 5 minutes at low speed (3000 x g) at roomtemperature.5. Transfer the upper aqueous phase to an endotoxinfree container.6. Proceed with the DNA purification by any method.Use endotoxin-free buffers and containers. References1. Bordier, C., J. Biol. Chem., 256, 1604-1607, (1981).2.
