DBCO-PEG-Biotin

This series of heterobifunctional reagents, including Dibenzocyclooctyne-PEG-Biotin and DBCO-PEG-Biotin, combines a DBCO group for copper-free click chemistry with azides and a biotin moiety for high-affinity streptavidin binding. The DBCO enables efficient conjugation under physiological conditions, while the biotin allows robust capture or detection in assay systems. These reagents are particularly suitable for labeling biomolecules, preparing diagnostic probes, and developing affinity-based purification platforms.
