Affymetrix, Inc. launched its Anatrace brand Neopentyl Glycol (NG) Class Detergents, the next generation of detergents to significantly advance the study of integral membrane proteins (IMPs), the most important proteins found in the human genome. Developed by leading chemists, and available only from Affymetrix, the NG Class represents a new family of detergents based on the maltose-neopentyl amphiphile design first described in a study recently published in the journal Nature Methods1. The new NG Class was found to be more capable than current leading detergents, such as n-dodecyl-?-D-maltoside (DDM), in promoting crystallization of IMPs in preparation for structural and functional studies.
“We are excited to make this breakthrough available to life scientists who are intrigued by the mystery of these essential and pervasive proteins,” said Andy Last, Chief Commercial Officer at Affymetrix. “Our new NG Class Detergents give biologists enhanced tools to solve the structure of membrane proteins using advanced techniques, such as nuclear magnetic resonance and X-ray diffraction.”
Membrane proteins are important because they mediate the transfer of materials and signals between cells and their environment, and they account for a large portion of the human genome’s coding region. Moreover, they are the target of 50 percent of current pharmaceutical agents. Using most conventional detergents, IMPs can be successfully extracted. However, due to the hydrophobic nature of membrane proteins, they tend not to stabilize and become denatured and/or aggregated after extraction. If IMPs are not stabilized enough to crystallize, then they cannot be effectively studied, nor fully understood.
Because membrane proteins have diverse sequences, shapes, and properties, Affymetrix is launching a suite of three Anatrace brand NG Class Detergents as substitutes for the three most popular glucoside detergents, lauryl and decyl maltosides and octyl glucoside.
