I. [Product Description]
CPP-PEG-ICG is a near-infrared fluorescently labeled organic intermediate based on the covalent coupling of cell-penetrating peptides (CPP) and polyethylene glycol (PEG). It has excellent biocompatibility and targeted modification capabilities. This compound can be used as a pharmaceutical intermediate to construct the core module of functionalized nanocarriers. Its PEG segment can significantly enhance water solubility and stability, and the ICG part endows it with near-infrared fluorescence tracking properties, making it suitable for efficient catalytic coupling reaction systems.
