I. [Product Description]
Biotin-PEG-OPSS is a multifunctional organic intermediate. Through the precise coupling of biotin and the dithiopyridine (OPSS) group, combined with the excellent water solubility and biocompatibility of the PEG chain, it is widely used in bioconjugation reactions and surface modification of nanomaterials. This compound can serve as an efficient catalyst or linking arm, providing a stable and reliable chemical platform for the functional modification of proteins, antibodies, and nanoparticles.
