Thermo Scientific Sodium Cholate is an ionic detergent that is especially useful for liposome preparation and lipid isolation.
Sodium cholate (cholic acid) is a water-soluble, bile-acid commonly used in protein methods such as cell lysis, liposome preparation, isolation of membrane proteins and lipids, preventing nonspecific binding in affinity chromatography and as a cell culture media supplement.
 

Highlights:

  • Anionic, bile-acid detergent for many laboratory uses
  • Effective for liposome preparation and lipid isolation
  • Can be removed from solution by dialysis
  • High-purity compound with low UV absorptivity

Product Details:

At concentrations above 2mM, cholate will form micelles having MW ~900 to 1200. The small size of these micelles allows them to be easily remove by dialysis or gel filtration if needed. Note: removal of a detergent from a protein solution my result in protein precipitation and/or aggregation.
