Sodium Cholate is water soluble ionic detergent/bile salt commonly used in applications ranging from cell lysis, liposome preparation, isolation of membrane proteins and lipids, preventing nonspecific binding in affinity chromatography and as a cell culture media supplement.

- The effectiveness of a detergent in any application is dependent on the detergents concentration. Too much or too little detergent can often have a deleterious effect. It is recommended that researchers examine a variety of detergent concentrations in their application.
- At concentrations above 9.5 mM, cholate will form micelles having MW ~900-1200. The small size of these micelle allows them to be easily removed by dialysis or gel filtration if needed.
- Note: removal of a detergent from a protein solution my result in protein aggregation.
