Opis

Zastosowanie

A membrane permeable, nonfluorescent reagent . This fluorochrome enters the cell cytoplasm, where its acetic group is cleaved by intracellular, nonspecific esterases, which forms the impermeable, fluorescent form of the molecule. Utilized as a phloem-mobile symplasmic tracer having staining characteristics that differ from the commonly used CFDA (5-(6-)carboxyfluorescein diacetate).

suitable as fluorogenic substrate for esterases

Inne uwagi

Highly water soluble enzyme substrate for the fluorimetric assay of esterases at longwave excitation and emission wavelengths
