General description

Dimethylethylammoniumpropane sulfonate is a zwitterionic solubilizing agent with usefulness in protein crystallization.

Application

Dimethylethylammoniumpropane sulfonate has been used in a study to assess the functional properties of the separate subunits of the human DNA helicase II/Ku autoantigen. It has also been used in a study to investigate the swelling behaviors of copolymeric hydrogels in various saline solutions.
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.

The Ku antigen consists of two subunits of 70 and 83 kDa and is endowed with both duplex DNA end-binding capacity and helicase activity (human DNA helicase II). HeLa Ku can be isolated from in vitro cultured human cells uniquely

The potential usefulness of the new zwitterionic solubilizing agent, dimethyl ethylammonium propane sulfonate (NDSB195), in protein crystallization was shown using hen egg-white lysozyme. In the presence of this agent, highly diffracting crystals were obtained using ammonium sulphate as a precipitant
