Cy7.5-hydrazide,Cy7.5-HZ,Cy7.5-酰肼,Cyanine7.5-hydrazide,Cyanine7.5-HZ,Cyanine7.5-酰肼
A carbonyl-reactive hydrazide derivative of Cyanine7.5 near infrared (NIR) fluorophore. This dye has similar spectral properties with ICG (indocyanine green), but has a higher quantum yield of fluorescence. Hence, this fluorophore is ideal for in vivo imaging.
This is a carbonyl-reactive dye which is particularly useful for the labeling of antibodies after periodate oxidation. It also labels other carbonyl compounds (aldehydes and ketones), for example, many saccharides.

Cyanine7.5 近红外 (NIR) 荧光团的羰基反应性酰肼衍生物。这种染料具有与 ICG(吲哚菁绿)相似的光谱特性，但具有更高的荧光量子产率。因此，这种荧光团是体内成像的选择。
这是一种羰基反应性染料，特别适用于高碘酸氧化后的抗体标记。它还标记其他羰基化合物(醛和酮)，例如许多糖类。
