Cyanine5 hydrazide is a reactive dye for the labeling of aldehydes and ketones, an analog of Cy5® hydrazide.

This dye reacts smoothly and nearly quantitatively with various carbonyl groups encountered in biomolecules. Examples are proteins subjected to oxidative stress, glycosylated proteins pre-activated by periodate oxidation (including antobodies), and oligonucleotides with aldehyde moieties.

Cyanine5 hydrazide replaces carbonyl-reactive Cy5®, DyLight 649 dyes.
