DSPE-PEG2k-CGPLGVRGDK-DBCO

DBCO(Dibenzylcyclooctyne) reagents can be used to label azide-modified biomolecules spontaneous without the need for toxic Cu catalysts.The reaction of azides with strained alkynes,such as cyclooctynes, readily forms a triazole product without the need for a toxic catalystPEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins.It can also suppress the non-specific binding of charged molecules to the modified surfaces.It can also couple various peptides.
