Fluorescent CF® Dye hydrazides are bright, extremely water-soluble, nontoxic molecules, useful as aldehyde-fixable cell tracers. They can also be used to label aldehyde or ketone groups of polysaccharides, carbohydrates or glycoproteins.

• Fluorescently labeled low molecular weight, polar, non-toxic molecules; useful as aldehyde-fixable cell tracers
• Membrane impermeant, can be easily loaded into cells by microinjection
• Can be used to fluorescently label aldehyde or ketone groups of polysaccharides, carbohyrdates, or glycoproteins
• Bright, photostable and water-soluble CF® Dyes are excellent options for fluorescent imaging

Bright, extremely water-soluble and non-toxic CF® Dye hydrazides are excellent fluorescent tracers for neurons or gap junction studies. The cell impermeant tracer dyes can be introduced into cells by microinjection.

CF® Dye hydrazides can also be used to fluorescently label aldehyde or ketone groups of carbohydrates or glycoproteins molecules after peroxidation with periodate.

For carbohydrates labeling applications, we recommend using CF® Dye aminooxy forms, which are more reactive toward these groups than hydrazide forms. For fluorescence two-dimensional differential gel electrophoresis (2D-DIGE), we recommend CFDI hydrazides.
