Cyanine5 tetrazine

Description

Cy5 hydrazide is a cyanine dye containing hydrazide, which can be used to label aldehydes and ketones. This reagent allows to label various carbonyl-containing molecules such as antibodies and other glycoproteins after periodate oxidation, proteins after oxidative stress or deamination, or reducing saccarides.

Cyanine5 hydrazide replaces carbonyl-reactive Cy5, Alexa Fluor 647, DyLight 649 dyes.

Uses

Cy 5 hydrazide (Cyanine5 hydrazide) is a fluorescent dye for aldehydes and ketones. Cy 5 hydrazide can be used for labeling proteins[1].
