AF 488 is a stable dye over a broad pH range (from 4 to 10) with the fluorescence peak in the green region (at 519 nm).
Conjugates of biomolecules with AF 488 can be used in flow cytometry, for example in multicolor staining. AF 488 is also used in cell microscopy due to its high photostability.
AF 488 amine is soluble in water and can be conjugated with electrophiles and participate in enzymatic transamination.
