Synthetic detergent with a C16 alkyl chain. Useful for solubilizing proteins for 2D-analysis. ASB-16 shows better protein solubilization properties than CHAPS and in some cases than ASB-14, resulting in improved detection of membrane proteins by 2D-electrophoresis.

Synonym: Amidosulfobetaine-16; 3-[N,N-Dimethyl-N-(3-palmitamidopropyl)-ammonio]-propane-
1-sulfonate

CAS registry number: [52562-29-5]

Molecular formula: C24H50N2O4S

Relative molecular mass: 462.7

Classification: Zwitterionic surfactant

Critical micellar concentration (CMC): 8 mM
