I. [Product Description]
Biotin-PEG-SH (Biotin-Polyethylene Glycol-Thiol) is a multifunctional organic intermediate that combines the high affinity of biotin with the steric hindrance regulation properties of the PEG chain. It can be used as a pharmaceutical intermediate for targeted bioconjugation or surface modification. The terminal thiol group provides directional coupling ability. Combined with the adjustable molecular weight characteristics of PEG, it has important application value in the bioconjugation reaction of biological macromolecules with the participation of a catalyst.
