Description
Biotin-PEG4-Azide is a click chemistry conjugation reagent featuring a biotin moiety linked to an azide group via a PEG4 spacer. This compound enables efficient biotin labeling of alkyne-containing molecules through copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. It is widely applied in chemical biology research for biomolecule detection, affinity purification, and the development of bioconjugate probes.
