compound introduction
Diazo Biotin-PEG3-DBCO is useful for introducing a biotin moiety to azide-containing biomolecules using copper-free Click Chemistry. The hydrophilic spacer arm provides better solubility to the labeled molecules in aqueous media. Diazo allows efficient release of captured biotinylated molecules from streptavidin using sodium dithionite (Na2S2O4).
