CY5.5-COOH（Cat No.:I041056）is a fluorescent dye commonly used in molecular biology and biochemistry for labeling and imaging applications. It is a derivative of the cyanine dye family, characterized by its strong fluorescence in the near-infrared (NIR) spectrum, which allows for improved tissue penetration and reduced background interference in biological samples. The carboxyl group (COOH) at the end of the molecule enables conjugation to various biomolecules, such as proteins, antibodies, or nucleic acids, making CY5.5-COOH ideal for fluorescence-based assays, flow cytometry, and in vivo imaging of cellular and molecular processes.
