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.

Cyanine3 hydrazide 是一种羰基活性染料,是 Cy3® 酰肼的类似物。

该试剂可以标记各种含羰基分子,例如高碘酸氧化后的抗体和其他糖蛋白、经历氧化应激或脱氨基作用的蛋白质或还原糖。 Cyanine3 与许多荧光仪器兼容。
