(Arg)₉, FAM-labeled（Cat No.:I044278）is a synthetic peptide composed of nine consecutive arginine residues, known for its strong cell-penetrating capabilities. The polyarginine sequence facilitates efficient translocation across cellular membranes via endocytosis or direct penetration, making it a widely used cell-penetrating peptide (CPP). The FAM (fluorescein amidite) label provides green fluorescence, enabling real-time visualization and tracking in live-cell imaging and uptake studies. This conjugate is commonly employed in drug delivery, molecular transport assays, and intracellular trafficking research, offering a powerful tool for studying peptide-based delivery systems and cellular internalization dynamics.
