I. [Product Description]
Aminooxy-PEG-Poly-Arginines is a multifunctional organic intermediate with both efficient coupling ability and biocompatibility. The aminooxy group in its structure can serve as a specific coupling site, reacting rapidly with aldehyde/ketone groups. The PEG chain provides excellent solubility and stability, while Poly-Arginines endows the molecule with strong cell penetration. This compound is widely used in the fields of bioconjugation, catalyst carriers, and modification of polymer materials.
