Product Description: Cyanine7.5 azide chloride is a dye derivative of Cyanine 7.5 (Cy7.5) (HY-D0926) with an azide functional group. Cy7.5 is a near-infrared fluorescent dye commonly used for biolabeling and cell imaging. The azide group of Cyanine7.5 azide chloride can react chemically with molecules containing alkyne functionality, such as alkyne or cyclooctyne, to form covalent bonds. Therefore, Cyanine7.5 azide chloride can bind to biomolecules such as proteins and antibodies to track their location and dynamic changes in biological samples.
