Dodecylphosphocholine-d38 is intended for use as an internal standard for the quantification of dodecylphosphocholine by GC- or LC-MS. Dodecylphosphocholine is a detergent that is commonly used for membrane protein structure determination using NMR. It has also been used to generate membrane mimetic micelles and to characterize pore formation by the influenza M2 transmembrane domain within a synthetic membrane. Dodecylphosphocholine micelles induce amyloid fibril formation by the prion protein (PrP) β-strand (PrP (110-136)). Dodecylphosphocholine has a critical micelle concentration (CMC) of approximately 1.5 mM.
