Product Name

Endotoxin Removal solution, Remove lipopolysaccharides (LPS) from plasmid DNA preparations

Quality Level

200

Application

Endotoxin Removal solution has been used to remove lipopolysaccharide (LPS) from Baker′s yeast RNA.

Biochem/physiol Actions

The reagent relies on the micellar properties of Triton X-114 to remove endotoxins from solution. When warmed above 20 °C, micelles aggregate into a separate phase that sequesters amphiphilic solutes, including lipopolysaccharides. The hydrophilic DNA remains in the aqueous phase.

Preparation Note

1 volume treats 5 volumes of DNA solution (≤1mg/ml)

Storage Class

10 - Combustible liquids

Endotoxin (lipopolysaccharide, LPS) is commonly found as a contaminant in plasmid DNA preparations. We demonstrate here that the quantities of LPS typically contaminating DNA preparations can generate a toxicity to primary cells (primary human skin fibroblasts, primary human melanoma cells)
