Application

2-[4-(Dimethylamino)styryl]-1-ethylpyridinium iodide (DASPEI) has been used for the labelling of hair cells in larval zebrafish.[1]

Biochem/physiol Actions

2-[4-(Dimethylamino)styryl]-1-ethylpyridinium iodide (DASPEI) accumulates in the mitochondria and has a large fluorescence Stokes shift. It is also used for the relative measurements of mitochondrial membrane potential.[2]
Suitable as a mitochondrial stain in live cells.
