Sulfo-Cy7.5 azide

Description

Sulfo-Cy7.5 azide is a Cyanine 7.5 Cy7.5 HY-D0926 dye derivative with azide and sulfonate functional groups. The sulfonate ion increases the water solubility of the compound, making it suitable for use in aqueous solutions. Cy7.5 is a near-infrared fluorescent dye commonly used for biolabeling and cell imaging. The azide group of Sulfo-Cy7.5 azide can react chemically with molecules containing alkyne functionality, such as alkyne or cyclooctyne, to form covalent bonds. Therefore, Sulfo-Cy7.5 azide can bind to biomolecules such as proteins and antibodies to track their location and dynamic changes in biological samples. It contains an azide group and can undergo copper-catalyzed azide-alkyne cycloaddition CuAAc with molecules containing alkyne groups. It can also undergo ring strain-promoted alkyne-azide cycloaddition SPAAC with molecules containing DBCO or BCN groups.
