Properties

Description

N-(azido-PEG4)-biocytin is a biotin PEG linker featuring a carboxylic group and an azide group. The carboxylic group readily forms stable, irreversible amide bonds with primary amino (-NH₂) groups. The azide group allows for conjugation with alkyne moieties in Cu(I)-catalyzed Click Chemistry reactions or DBCO moieties in copper-free Click Chemistry reactions, forming stable triazole linkages. Additionally, the inclusion of a hydrophilic PEG spacer enhances the solubility of the biotin-conjugated molecules in aqueous media.
