cRGD-PEG-SH

cRGD-PEG-SH is a linear heterobifunctional PEG reagent with cyclic peptide cRGD and sulfhydryl groups at both ends of the molecular chain. Applications of RGD peptides include inhibition of apoptosis, angiogenesis and tumorigenesis. 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. The sulfhydryl groups at the molecular chain end selectively react with maleimides and transition metal surfaces (Including Gold, Silver, etc.). cRGD-PEG-SH is an effective target material that can be used as an anti-tumor drug carrier and for effective targeted delivery.
