DBCO-PEG4-Biotin is an azadibenzocyclooctyne-biotin derivative that contains a biotin group and four PEG units. It functions as a versatile biotinylation reagent, enabling the introduction of a biotin moiety to azide-labeled biomolecules. This process occurs through a copper-free strain-promoted alkyne-azide click chemistry (SPAAC) reaction. It is a click chemistry reagent, featuring a DBCO group that facilitates strain-promoted alkyne-azide cycloaddition (SPAAC) with azide-containing molecules.
- Azadibenzocyclooctyne-biotin derivative
- Contains a biotin group and 4 PEGs
- Versatile biotinylation reagent
- Used for introducing a biotin moiety to azide-labeled biomolecules
- Utilizes copper-free strain-promoted alkyne-azide click chemistry (SPAAC)
- Contains a DBCO group for SPAAC with azide groups
- For research use only
