CF™633 hydrazide is superior far-red fluorescent dye with a hydrazide reactive group. CF™633 dye is brighter and far more photostable than Alexa Fluor® 647 when excited by the 633 or 635 nm laser (download the CF™633 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.
