General description

A water soluble, amphiphilic α-helical, non-denaturing lipopeptide detergent (LPD) that forms small micelles (CMC ﹤1 µM; micelle MW ~23,100; aggregation number ~8.1; partial specific volume ~0.77 cm³/g) and effectively mimics lipid bilayers. Shown to solubilize as well as stabilize bacteriorhodopsin, lactose permease and E. coli PagP protein ([LPD] ~250 µM and [protein] ~22 µM) by forming complexes and precluding aggregation. Useful for NMR and X-ray structural studies of membrane proteins.

A water soluble, amphiphilic α-helical lipopeptide detergent (LPD) that forms small micelles and effectively mimics lipid bilayers (solubility in PBS ~ 40 mM; micelle MW ~ 23,100; aggregation number ~ 8.1; partial specific volume ~ 0.77 cm³/g). Shown to not only solubilize but also stabilize bacteriorhodopsin, lactose permease and E. coli PagP protein ([LPD] ~ 250 µM and [protein] ~ 22 µM) by forming complexes and precluding aggregation. Useful for NMR and X-ray structural studies of membrane proteins.
