Biotin-PEG-DBCO

Biotin-PEGn-DBCO is primarily used for copper-free click chemistry bioconjugation, enabling efficient labeling, purification, and detection of azide-modified biomolecules (e.g., proteins, antibodies, or nanoparticles) via the high-affinity streptavidin-biotin system. Its key benefits include enhanced water solubility, reduced steric hindrance due to the PEG spacer, and biocompatibility, making it ideal for sensitive applications like live-cell imaging, targeted drug delivery, and diagnostic assays
