Biotin-PEG8-alcohol（Cat No.:I014224）is a versatile bioconjugation reagent that combines a biotin moiety for high-affinity streptavidin/avidin binding with a terminal hydroxyl group for further chemical derivatization. The PEG8 spacer provides extended length, flexibility, and hydrophilicity, improving solubility and reducing steric hindrance in complex biological environments. This design ensures accessibility of the biotin while offering a functional handle for additional modifications. Widely employed in proteomics, chemical biology, imaging, and drug discovery, Biotin-PEG8-alcohol enables controlled labeling, affinity capture, and surface functionalization for diverse research and biomolecular engineering applications.
