Cy5.5 hydrazide is a reactive 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. Cyanine5.5 is an analog of Cy5.5 and is suitable for in vivo NIR imaging applications. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
