Cyanine7.5 hydrazide;Cy7.5 hydrazide

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.
