2H-Cho-Arg (trifluoroacetate salt) is a steroid-based cationic lipid that contains a 2H-cholesterol skeleton coupled to an L-arginine head group and can be used to facilitate gene transfection. 2H-Cho-Arg forms a complex with plasmid DNA (pDNA) and decreases pDNA migration in an electrophoretic mobility shift assay at +/- charge ratios of 4 or higher. Reagent grade, for research use only.
