Non-ionic detergents have a hydrophilic head group that is uncharged and are preferred for their ability to break lipid-lipid and lipid-protein interactions. They have limited ability to break protein-protein interactions and are often referred to as non-denaturing detergents and are used to isolate biologically active membrane proteins.
The non-ionic deteregents are supplied as a general Research Grade, Proteomic Grade (PG) Solutions and 2D-Detergents™. The Proteomic Grade (PG) Solutions have ultra low aldehyde (<100μM) and peroxide (<50μM) concentrations to reduce the effects of peroxidase and carbonyl compounds that negatively interact with membrane proteins. The 2D-Detergents™ have low conductivity (<10μS) and ultra low aldehyde (<100μM) and peroxide (<50μM) concentrations.
