I. [Product Description]
RGD-PEG-SS-PEI is a multifunctional organic intermediate constructed based on integrin-targeting peptide (RGD), polyethylene glycol (PEG), disulfide bond (SS), and polyethyleneimine (PEI). It has precise targeting, redox responsiveness, and cationic polymer characteristics. Its amphiphilic block structure is suitable for the development of drug delivery systems and can be used as a key component for pharmaceutical intermediates or biomaterial modification. The molecular weight can be custom-designed to meet different experimental needs.

II. [Product Details]
    【Appearance】 Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid.
    【Stability】 Store refrigerated and avoid repeated freeze-thaw cycles.
    【Solvent】 Conventional organic solvents such as chloroform, dichloromethane, and DMSO.
    【Molecular Weight】 (PEG): 2000, 3400, 5000. Other molecular weights can be customized.
    【Storage Conditions】 Store at a low temperature below 4°C in a sealed and dry environment.
▪ Precautions: ▶ To ensure product stability, please note that the package should be opened for use only after constant temperature drying!

III. [Application Fields]
    1. Construction of targeted nanodelivery systems (based on the specific binding of RGD to integrins).
    2. Development of redox-sensitive drug carriers (controllable cleavage of SS bonds).
    3. Preparation of gene/protein complexes mediated by cationic polymers (charge effect of PEI).
    4. Surface functionalization modification of biomaterials (anti-protein adsorption property of PEG).
    5. Synthetic research of multi-stage responsive intelligent materials.
