生物素-PEG3-疊氮化物是一種不可裂解的疊氮化物活化生物素化試劑利用好，通過銅催化的點擊反應與末端炔烴反應反應資源優勢，通過無銅點擊反應與應變的環(huán)辛炔（例如DBCO或BCN化合物）反應技術創新，或通過稱為Staudinger化學的機制與磷化氫標記的分子反應統籌，從而實現(xiàn)生物樣品中衍生化分子的高效和特異性偶聯(lián)先進的解決方案。這些反應是生物正交的攻堅克難，或者換句話說各有優勢，與生物系統(tǒng)相容影響，因為它的成分不與生物環(huán)境發(fā)生反應自然條件。

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.
