The optical properties of the Cy3.5 amine labeling experiment are an important reason for its application in biomarkers and fluorescence imaging. Cy3.5 is a fluorescent dye belonging to the Cyanine dye family, with high molar extinction coefficient and quantum yield, making it excellent in trace analysis and fluorescence imaging.

In the Cy3.5 amine labeling experiment, the dye covalently binds to specific functional groups on biomolecules (such as proteins, nucleic acids, etc.) through its amine group, thereby achieving the labeling of the target molecule. This labeling not only maintains the biological activity of the target molecule, but also endows it with fluorescence characteristics, making it convenient for qualitative and quantitative analysis in complex biological samples.

The maximum excitation wavelength of Cy3.5 dye is usually in the range of 550-570nm, while the maximum emission wavelength is in the range of 570-590nm. This gives Cy3.5 dye unique emission characteristics between green and red fluorescence, enabling good spectral separation from other commonly used fluorescent dyes such as GFP, FITC, etc., avoiding signal interference.

In addition to fluorescent signals with high sensitivity and specificity, Cy3.5 dyes also exhibit good photostability. Under continuous laser irradiation, its fluorescence signal can remain relatively stable and is not prone to bleaching or quenching. This makes Cy3.5 dye have better application prospects in long-term fluorescence imaging experiments.

In summary, the optical properties of the Cy3.5 amine labeling experiment make it a tool in the fields of biomarkers and fluorescence imaging. Its high sensitivity, specificity, good spectral separation, and excellent photostability make this dye valuable in biomedical research.
