Pyrene-PEG5-biotin contains a pyrene group and biotinylation reagent. Pyrene can be used in the surface functionalization of carbon nanotube and graphene, graphene oxide, reduced graphene oxide. Pyrene shows strong pi-pi stacking between the pyrene and the aromatic rings on single wall and multi-walled carbon nanotubes. The biotinylation can react with amine molecules in the presence of activator EDC or HATU. PEG attached to the biotin gives an extended spacer arm that permits the biotin to reach into the binding pocket of the protein. The PEG moiety also increases solubility of Biotin-PEG conjugates considerably. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
