D Illinger et al.
Biology of the cell, 71(3), 293-296 (1991-01-01)
The fluorescent hydrophobic plasma membrane probe, trimethylamino-diphenylhexatriene (TMA-DPH) was previously shown to follow the plasma membrane throughout its internalization and recycling process and thus to behave as a marker for endo- and exocytosis in living cell systems. In this paper
J G Kuhry et al.
Cell biophysics, 5(2), 129-140 (1983-06-01)
Fluorescence intensity measurements and fluorescence microscopy data showed that TMA-DPH (trimethylammonium diphenylhexatriene), a cationic derivative of the fluorescence polarization probe DPH, has a considerably different behavior in L929 cultured cells than does its parent molecule. In contrast to DPH, it
