Cy7 NHS ester
Product Introduction：
Amino active Cy7, a near-infrared fluorescent dye. This reagent can be used to generate Cy7-labeled biomolecules for further small animal in vivo imaging studies, drug design and related experiments. The Cy7 center strengthens the structural characteristics of the polymethylene chain, which increases the quantum yield by 20% compared with the parent structure and increases its fluorescence brightness.
