Bifunctional triethyleneglycol (PEG3) linker with biotin and hydroxyl moieties. The terminal hydroxyl group in the crosslinker can react with esters, azides, amines, and halogen derivatives in various conditions. Biotin-labeled biomolecules can be bound to avidin or streptavidin for further purification and detection.

This structure of biotin azide features a long hydrophilic PEG3 linker that separates biotin residue from the target molecule for efficient binding with streptavidin. Its linker also enhances aqueous solubility to facilitate conjugation.
