Di-4-ANEPPS colorant pour membranes, pour histologie
Di-4-ANEPPS
Di-4-ANEPPS is a fast-responding membrane potential dye. Changes in the membrane potential of the cell correlate with changes in the fluorescence excitation intensity of the dye.
- λEx/λEm (MeOH) = 496/705 nm*
- Orange red solid soluble in DMF, ethanol or DMSO
- Store at 4°C and protect from light, especially in solution
Di-4-ANEPPS is internalized in cells rapidly, so it is mainly used for short-term experiments. We also offer Di-8-ANEPPS (catalog number 61012), which is more lipophilic and better retained in the outer leaflet of the plasma membrane.
* Note that the spectra of styryl dyes generally undergo a large blue shift in lipids compared to organic solvent. See the spectra for styryl dyes in liposomes under product images.
