结构式：

CY7 alkynes are a fluorescent dye used for biological coupling and imaging applications. It belongs to the cyanine dye category with a molecular weight of 622.28 and is soluble in DMSO, DMF, and alcohols. It has an excitation wavelength of 750nm and an emission wavelength of 773nm. CY7 alkynes can effectively label biological molecules such as proteins, nucleic acids, and carbohydrates. This is due to the existence of alkynyl groups, which can easily react with azides using click chemistry. The obtained biocouples are stable and can be observed using fluorescence microscopy or flow cytometry. CY7 alkynes can also perform long-term imaging of living cells and tissues due to their photostability.
