Sulfo-Cy7.5 maleimide（Cat No.:I042809）is a fluorescent dye used primarily in bioimaging and molecular biology applications. It features a sulfonated Cy7.5 fluorophore, which enables near-infrared fluorescence for high sensitivity in imaging techniques, and a maleimide group that allows for covalent attachment to thiol groups on biomolecules such as proteins, peptides, or antibodies. This conjugation provides a powerful tool for tracking and visualizing specific molecules or cells in live animals or in vitro. Sulfo-Cy7.5 maleimide is commonly used in fluorescence-based assays, imaging studies, and targeted drug delivery research.
