Sodium deoxycholate (deoxycholic acid) is a water-soluble, bile-acid, ionic detergent commonly used in protein methods. It is most frequently used as a component of cell lysis buffers (e.g., RIPA buffer), but also has been used for liposome preparation, isolation of membrane proteins and lipids, preventing non-specific binding in affinity chromatography and a cell culture media supplement.
The effectiveness of a detergent in any application depend upon the detergent's concentration. Too much or too little detergent can often have a deleterious effect. It is recommended that you examine a variety of detergent concentrations in your application. At concentrations above 2 mM, cholate will form micelles having MW ~2000. The small micelle size allows easy removal by dialysis or gel filtration when needed. Note: removal of a detergent from a protein solution may result in protein precipitation and/or aggregation.
Sodium deoxycholate is the detergent recommended for stripping endotoxin (Lipopolysaccharide or LPS) from immobilized Polymyxin B columns. This is the recommended product for use with the Thermo Scientific Detoxi-Gel Endotoxin Removing Gel.
