Lumiprobe Cy3 酰肼 Cyanine3 hydrazide
Cyanine3 hydrazide is a carbonyl-reactive dye, an analog of Cy3® hydrazide.
This reagent allows to label various carbonyl-containing molecules such as antibodies and other glycoproteins after periodate oxidation, proteins which have undergone oxidative stress or deamination, or reducing saccarides. Cyanine3 is compatible with a number of fluorescent instruments.
