Sulfo-Cy7.5 amine(CAT: I040254) is a water-soluble near-infrared (NIR) fluorescent dye derivative of Cyanine 7.5 (Cy7.5, HY-D0926), featuring a reactive amine group for bioconjugation. The presence of sulfonate groups enhances aqueous solubility, facilitating efficient labeling in physiological environments. The amine functionality enables covalent coupling with carboxyl-containing biomolecules, such as proteins and antibodies, via amide bond formation. Sulfo-Cy7.5 amine is widely used in cell imaging, biolabeling, and in vivo tracking, offering high fluorescence intensity and minimal background interference. It is ideal for applications requiring precise molecular visualization, dynamic tracking, and NIR fluorescence-based assays.
