DDMAB (CAS 15163-30-1)

Dodecyl(dimethyl)amine-N-oxide (DDMAB) is a quaternary ammonium compound commonly used as a surfactant and a cationic detergent in various research applications. Its mechanism of action is based on its amphiphilic nature, possessing both hydrophobic and hydrophilic regions. In research, DDMAB is frequently employed in membrane protein studies, particularly in the solubilization and purification of integral membrane proteins due to its ability to disrupt lipid-lipid and lipid-protein interactions within the lipid bilayer. DDMAB′s positively charged headgroup interacts with the negatively charged phospholipid headgroups, leading to the formation of mixed micelles that encapsulate hydrophobic regions of membrane proteins, effectively solubilizing them in aqueous solutions. Moreover, DDMAB has been utilized in various biophysical and biochemical assays, including protein crystallization, nuclear magnetic resonance (NMR) spectroscopy, and electron microscopy, enabling structural and functional studies of membrane proteins. Additionally, its compatibility with a wide range of experimental conditions and its relatively mild detergent properties make DDMAB a valuable tool in membrane protein research, facilitating the investigation of membrane protein structure-function relationships and the development of novel targets for membrane-associated processes.
