Protein-detergent interactions studied by capillary isotachophoresis.
The interactions of sodium dodecyl sulphate with bovine serum albumin and ovalbumin have been studied by capillary isotachophoresis. This method makes it possible to determine very accurately the number of ligands bound to the high-affinity binding sites of the native protein. Bovine serum albumin was found to have seven high-affinity binding sites whereas ovalbumin in its native state was found to lack high-affinity binding sites for dodecyl sulphate.
