I. [Product Description]
SS-PEG-Lysines is a disulfide bond-modified polyethylene glycol-lysine complex. As a high-end organic intermediate and bioconjugation catalyst, it combines the dynamic responsiveness of disulfide bonds and the spatial stability of PEG. Its lysine group provides highly efficient reactive sites and is suitable for constructing the core structural unit of intelligent responsive nanocarriers.
