General description
Dimethyl-2-hydroxyethylammoniumpropane sulfonate, or NDSB 211, is a nondetergent-sulfobetain. It is zwitterionic over a wide pH range, easily removed by dialysis and shows no significant absorption in the near UV range.
Application
NDSB 211 has been used in a study to assess halophilic protein stabilization by the mild solubilizing agents nondetergent sulfobetaines. It has also been used in a study to investigate an alternative strategy for crystallizing macromolecules.
Non-detergent sulfobetaine is a compound used for non-denaturing protien purification. Increases the extraction yield of membrane, nuclear and cytoskeletal associated proteins. Zwitterionic over a wide pH range, easily removed by dialysis and no significant absorption in the near UV range. Specific applications include microsomal protein extraction, nuclear protein recovery, precipitation reduction in IEF, and membrane-bound protease purification.

In this work, experiments performed on pig heart and halophilic malate dehydrogenase as well as halophilic elongation factor Tu demonstrate a protein stabilization property from the recently described mild solubilizing agents nondetergent sulfobetaines. A practical application is given by the

Proteins of haloarchaea are remarkably unstable in low-ionic-strength solvents and tend to aggregate under standard two-dimensional (2-D) gel electrophoresis conditions, causing strong horizontal streaking. We have developed a new approach to generate 2-D maps of halophilic proteins which included washing
