DETAILS

Description (English)

Application
DASPEI can be used for staining mitochondria in live cells. This dye has a large fluorescence Stokes shift and is taken up relatively slowly as a function of membrane potential.
Biochem/physiol Actions
Suitable as a mitochondrial stain in live cells.
Other Notes
Staining of mitochondria in live cells1,2; uptake of dye by phospholipid vesicles3
