I. [Product Description]
Collagen-PEG-OPSS is a multifunctional organic intermediate that enables highly efficient and controllable bioconjugation reactions through the ortho-pyridyl disulfide (OPSS) group. Its core value lies in combining the biocompatibility of collagen, the molecular tunability of the PEG chain, and the reactivity of OPSS. It can be used as a pharmaceutical intermediate or catalyst in complex biomolecule modification systems.
