Cyanine7 hydrazide Usage And Synthesis

Uses

Cy7 hydrazides are Cy series dyes. Various cyanine 7 (Cy7) dyes have been used to label biomolecules for fluorescence imaging and other fluorescence-based biochemical analyses.

Description

Hydrazide derivative of Cyanine7, a NIR fluorescent dye, an analog of Cy7?._x000D_ _x000D_ This variety of heptamethine fluorophore contains a six-membered ring rigidizing the polymethine chain which allows to increase quantum yield by 20% compared to parent structure._x000D_ _x000D_ Hydrazide reacts quickly and smoothly with aldehydes and ketones yielding stable hydrazone products. This reaction is also good for the labeling of glycoproteins after periodate oxidation.
