生物素叠氮中文介绍：
生物素叠氮化物（PEG4羧酰胺-6-叠氮己基生物素）是不可裂解的叠氮化生物素化试剂，通过铜催化的点击反应与末端炔烃反应，产生稳定的三唑键。它还通过无铜的“点击化学"反应与环辛炔反应，形成稳定的三唑，不需要铜催化剂或高温。生物素叠氮化物允许用生物素选择性标记各种炔化分子（如DNA、寡核苷酸和蛋白质），以便随后使用链霉亲和素、亲和素或中性亲和素生物素结合蛋白进行检测或亲和®纯化。
Biotin Azide英文介绍：
Biotin Azide (PEG4 carboxamide-6-Azidohexanyl Biotin) is non-cleavable, azide-activated biotinylation reagent that reacts with terminal alkynes via a copper-catalyzed click reaction to produce a stable triazole linkage. It also reacts with cyclooctynes via a copper-free “click chemistry" reaction to form a stable triazole and does not require Cu-catalyst or elevated temperatures. Biotin Azide allows for selective labeling of various alkynylated molecules (such as DNA, oligonucleotides, and proteins) with biotin for the subsequent detection or affinity purification with streptavidin, avidin or NeutrAvidin® biotin-binding protein.
