I. [Product Description]
OPSS-PEG-tyrosine is a multifunctional organic intermediate with the characteristics of both pharmaceutical intermediates and bioconjugation catalysts. Its ortho-pyridyl disulfide bond (OPSS) enables efficient thiol-directed conjugation. The PEG chain provides excellent water solubility and adjustable molecular weight. The tyrosine residue endows it with the potential for targeted modification, making it suitable for the construction of complex molecular systems.
