CF™488A hydrazide is a superior green fluorescent dye with a hydrazide reactive group. CF™488A dye is exceptionally bright and photostable, making it an excellent choice for fluorescence detection using 488 nm excitation (download the CF™488A flyer for more information). Our CF™ dye hydrazides are bright, extremely water-soluble and nontoxic. These properties make the dyes excellent fixable polar tracers for neurons, or for gap junction studies. The dyes can be introduced into cells by microinjection. Hydrazides also can be used for labeling aldehyde or ketone groups, such as carbohydrate molecules after peroxidation with periodate. However, for this application we recommend using CF™ dye aminooxy forms, which are more reactive toward these groups than hydrazide forms.Compatible with the NucleoCounter® NC-3000™.
