Biotin-PEG4-OH(CAT: I017013) is a biotinylated polyethylene glycol derivative featuring a biotin group linked through a four-unit PEG spacer and terminated with a hydroxyl group. The biotin moiety enables high-affinity binding to avidin or streptavidin, making it a key reagent in affinity purification, immobilization, and detection assays. The PEG4 spacer improves solubility, provides flexibility, and reduces steric hindrance, ensuring efficient interactions in complex biological environments. The terminal hydroxyl can be further functionalized for custom conjugation. Biotin-PEG4-OH is widely used in chemical biology, nanotechnology, and diagnostic research where reliable biotin–streptavidin coupling is required.
