APDye 488 Hydrazide is a bright, green-fluorescent dye that often used for labeling aldehydes or ketones in polysaccharides or glycoproteins. APDye 488 Hydrazide is useful as low molecular weight, membrane-impermeant, aldehyde-fixable cell tracers, exhibiting brighter fluorescence and greater photostability than cell tracers derived from other spectrally similar fluorophores.
