cRGD-PEG-NHS

cRGD-PEG-NHS is a linear heterobifunctional PEG reagent with cyclic peptide cRGD and active ester groups at both ends of the molecular chain. RGD peptides are used as coating surfaces for biomaterials to enhance drug delivery and imaging for disease diagnosis. PEGated RGDs can be cross-linked with other molecules through reactive end groups on PEGs and used in a variety of biomedical research. NHS is a good leaving group and can act with the amine containing part. cRGD-PEG-NHS can be easily incorporated into liposomes and other nanoparticles through the NHS-amine reaction. cRGD-PEG-NHS is an effective target material, which can be used as anti-tumor drug carrier and effective targeted delivery.
