Cy7.5 NHS ester（Cat No.:I042808）is a fluorescent dye used in molecular biology for labeling biomolecules, such as proteins, nucleic acids, and antibodies. The NHS ester group enables efficient covalent attachment to amine groups on target molecules, facilitating precise and stable labeling. This dye emits strong near-infrared fluorescence when excited, making it ideal for in vivo imaging, flow cytometry, and fluorescence microscopy. Its long-wavelength emission minimizes interference from autofluorescence, improving signal detection in complex biological samples. Cy7.5 NHS ester is widely used in research to study molecular interactions, cellular processes, and in vivo imaging applications.
