AF 555 amine (LP1K8C0)

AF 555 is a stable dye over a broad pH range (from 4 to 10) with the fluorescence peak in the yellow region (at 566 nm). Conjugates of biomolecules with AF 555 can be used in flow cytometry, for example in multicolor staining. AF 555 is also used in cell microscopy due to its high photostability. AF 555 amine is soluble in water and can be conjugated with electrophiles and participate in enzymatic transamination.
