Biotin-PEG3-Azide (CCT-AZ104)


Biotin-PEG3-Azide is non-cleavable, azide-activated biotinylation reagent that reacts with terminal alkynes via a copper-catalyzed click reaction, strained cyclooctynes (e.g. DBCO or BCN compounds) via Cu-free click reaction or with phosphine-labeled molecules by a mechanism known as Staudinger chemistry, enabling efficient and specific conjugation of derivatized molecules in biological samples. These reactions are bioorthogonal or in other words compatible with biological systems in that it′s components do not react with the biological environment.
