Cy7 hydrazide is a Cy7 dye linker. Cy7 has excitation and emission wavelengths at 750/773 nm. Hydrazide moieties react with aldehydes to form semi-permanent hydrazone bonds.
Cyanine7 hydrazide dichloride belongs to the cyanine dye series and is a common fluorescent marker for biomolecules that can interact with biomolecules. Cyanine dyes may also bind to double-helical DNA through intercalation and exhibit enhanced fluorescence upon binding.
