I. [Product Description]
SS-PEG-Poly-Arginines is a composite organic intermediate based on dynamic cross-linking of disulfide bonds. Through the synergistic effect of the flexible chain segment of polyethylene glycol (PEG) and the cationic property of polyarginine, it is endowed with excellent water solubility, biocompatibility, and reversible assembly ability. This compound can be used as an efficient catalyst carrier or a functionalized pharmaceutical intermediate, and is widely used in the fields of nanomaterial construction and bioconjugation technology.
