RGD-PEG-Cy3

RGD-PEG-Cy3 is a fluorescent labeling reagent that combines the Cy3 fluorescent dye, peptide (RGD), and polyethylene glycol (PEG) . The Cy3 fluorophore is commonly employed in applications such as immunolabeling, nucleic acid labeling, fluorescence microscopy, and flow cytometry, with a peak emission wavelength of approximately 562-570 nm. RGD is a peptide sequence (CRGDKGPDCiRGD) that targets tumor tissues specifically by binding to αvβ3 and αvβ5 integrin receptors, which are involved in tumor neovascularization.
