Biological Activity

[Description]:

DBCO-PEG4-Biotin is an azadibenzocyclooctyne-biotin derivative containing a biotin group and 4 PEGs. DBCO-PEG4-Biotin is a versatile biotinylation reagent used for the introduction of a biotin moiety to azide-labeled biomolecules via copper-free strain-promoted alkyne-azide click chemistry (SPAAC) reaction[1].
