DBCO-PEG4-Biotin

DBCO-PEG4-Biotin is a biotinylation reagent for labeling azide-containing biomolecules viacopper free Click Chemistry reaction. The hydrophilic PEG4 linker increase the solubility in aqueous media and reduces or eliminates aggregation and precipitation. The PEG linker in DBCO-PEG4-Biotin also enhances the accessibility of the biotin moiety, improving the detection efficiency of the biotinylated molecule.
