DBCO-PEG4-biotin is a click chemistry biotinylation that can enable copper-free click chemistry with azide molecules to form a stable triazole linkage. PEG4 spacer increases aqueou solubility of the molecules conjugated to the biotin compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
