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.
一种羰基活性酰肼衍生的Cyanine7.5近红外荧光团。这种染料和ICG（吲哚菁绿），但是有更高的荧光量子产率。因此，这种荧光团是活体成像的理想选择。
这种羰基活性染料对高碘酸氧化的抗体的标记尤其有效。它也可以用于羰基化合物（醛和酮），比如很多的糖类。
