Product Introduction
Sulfo-Cyanine7 maleimide is a thiol-reactive fluorophore that features a heptamethine cyanine dye structure, enabling its use in the labeling of biomolecules through maleimide-thiol conjugation chemistry. This fluorescent dye exhibits absorption and emission in the near-infrared region, making it suitable for bioimaging applications where deep tissue penetration and low background fluorescence are required. Sulfo-Cyanine7 maleimide is commonly used in fluorescence microscopy, flow cytometry, and other imaging techniques to facilitate the study of protein interactions and cellular processes.
