RGD-PEG-Cy3

RGD-PEG-Cy3 is a fluorescent labeling reagent that combines Cy3 fluorescent dye, peptide (RGD) and polyethylene glycol (PEG) . The Cy3 fluorophore is commonly used in applications such as immunolabeling, nucleic acid labeling, fluorescence microscopy, and flow cytometry. Cy3 has an emission maximum around 562-570 nm. RGD is a peptide sequence (CRGDKGPDCiRGD) that binds to αvβ3 and αvβ5 integrin receptors on tumor neovasculogenesis to achieve specific tumor tissue targeting[1].
