Biotin-PEG4-Picolyl azide is a biotin reagent which can be conjugated with alkyne-containing biomolecules. This biotin reagent incorporates a copper-chelating motif that dramatically accelerates the Cu(I)-catalyzed Click Chemistry. The use of Biotin Picolyl Azide instead of conventional Biotin Azide allows for at least a tenfold reduction in the concentration of the copper catalyst without sacrificing the efficiency of labeling. The hydrophilic spacer arm provides better solubility to the labeled molecules in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
