Description

Cy7 (Sulfo-Cyanine7) is a fluorescence labeling agent (Ex=750 nm, Em=773 nm). Cyanine dyes are used to label proteins, antibodies, peptides, and oligonucleotides[1].

In Vitro

Cyanine dyes such as Cy5.5 and Cy7, are excellent near-infrared (NIR) probes, possessing high molar absorptivity, good photostability and strong fluorescence emission[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
