Cyanine3 hydrazide,Cy3 hydrazide
目前Cyanine系列染料以兩種異構(gòu)體的形式存在，一種是非磺化花青素（non-sulfonated cyanines），一種是磺化花青素（sulfonatedcyanine）。兩者的光譜性質(zhì)幾乎*，因此大部分應(yīng)用可相互替換。

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 patible with a number of fluorescent instruments.
