NDSB-256 Dimethylbenzylammonium Propane Sulfonate A non-detergent sulfobetaine. Reported to prevent protein aggregation and facilitate the renaturation of chemically and thermally denatured proteins. Zwitterionic over a wide pH range. Easily removed by dialysis. At 1 M, NDSB-256 will restore 30% of the enzymatic activity of denatured egg white lysozyme; at 800 mM it will restore 16% of the enzymatic activity of denatured β-galactosidase.
