Biotin-PEG3-Azide

Biotin azide is a derivative of biotin (vitamin H) covalently bound with azide group. This reagent allows labeling of various alkynylated molecules (such as DNA, oligonucleotides, and proteins) with biotin. Biotin binding to avidin or streptavidin can be used in downstream affinity applications for the isolation of biotinylated molecules or their binding with streptavidin conjugates.

This structure of biotin azide features long hydrophilic linker which separates biotin residue from the target molecule for efficient binding with streptavidin. Its linker (PEG) also enhances aqueous solubility to facilitate conjugation.

The azide can be conjugated with various molecules using our recommended protocol.

生物素叠氮化物是与叠氮基共价结合的生物素（维生素 H）的衍生物。 该试剂允许用生物素标记各种炔基化分子（如 DNA、寡核苷酸和蛋白质）。 与亲和素或链霉亲和素结合的生物素可用于下游亲和应用，以分离生物素化分子或它们与链霉亲和素缀合物的结合。

生物素叠氮化物的这种结构具有长的亲水性接头，可将生物素残基与靶分子分开，从而与链霉亲和素有效结合。 它的接头 (PEG) 还增强了水溶性以促进结合。

使用我们推荐的方案，叠氮化物可以与各种分子结合。
