Description

Fluorescent probe for membrane fluidity measurements. Especially useful in the study of monolayer dynamics of lipoproteins and similar analogous systems.

DPH and its derivatives, TMA-DPH (N,N,N-Trimethyl-4-(6-phenyl-1,3,5-hexatrien-1-yl)phenylammonium p-toluenesulfonate, and DMA-DPH (1-[4-(Dimethylamino)phenyl]-6-phenylhexatriene, M1088 are cylinder-shaped and have fluorescence emission transition dipoles that are basically aligned parallel to their long molecular axis. As such, they are very sensitive to reorientation resulting from interactions with surrounding lipids. For this reason, they are used in fluorescence polarization studies of rotational motion and for membrane fluidity measurements.
