Di-8-ANEPPS
ANEPPS dyes are fast responding membrane potential dyes. Compared to Di-4-ANEPPS, Di-8-ANEPPS is better retained in the outer leaflet of cell plasma membranes and thus more suitable for long-term membrane potential studies. Di-8-ANEPPS is also more photostable and less phototoxic than Di-4-ANEPPS

Product Description
ANEPPS dyes are fast responding membrane potential dyes (1). Biotium offers both Di-4-ANEPPS and Di-8-ANEPPS. Di-4-ANEPPS has the problem of being rapidly internalized in cells, so it is mainly used for short-term experiments. However, because Di-8-ANEPPS is more lipophilic, the dye is better retained in the outer leaflet of cell plasma membranes and thus more suitable for long-term membrane potential studies. Di-8-ANEPPS is also more photostable and less phototoxic than Di-4-ANEPPS (2,3). In our tests, Di-8-ANEPPS also shows robust staining of liposomes, but poor staining of extracellular vesicles. Liposome staining with Di-8-ANEPPS is detectable in multiple channels using 488 nm excitation.
