Applications : Biotin azide allows labeling of various alkynylated molecules (like DNA, oligonucleotides, and proteins) with Biotin. 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 aquous solubility to facilitate conjugation.
