I. [Product Description]
CHO-PEG-Poly-Arginines (Aldehyde-Polyethylene Glycol-Polyarginine) is a multifunctional organic intermediate. Through the directional coupling property of the aldehyde group, the spatial stabilization effect of the PEG chain, and the positive charge property of polyarginine, it exhibits excellent performance in biological coupling, nanocarrier construction, and catalytic system design. Its modular structure supports precise modification and is suitable for the development of high-value-added pharmaceutical intermediates and the optimization of complex catalytic reaction systems.

III. [Application Fields]
    1. Development of nanomedicine carriers: The cationic property of polyarginine and the hydrophilic chain of PEG cooperate to construct stable nanomicelles.
    2. Targeted biological coupling: The specific binding of the aldehyde group to the amino group realizes site-specific modification of antibodies/proteins.
    3. Gene delivery system: The complexation of positively charged polypeptides with nucleic acids enhances cell penetration efficiency.
    4. Enzyme immobilization carrier: The three-dimensional spatial structure optimizes the exposure of catalytic active sites.
    5. Biomimetic material synthesis: Used for the assembly of intelligent materials with a biomimetic cell membrane structure.
