I. [Product Description]
OPSS-PEG-NHS is a multifunctional organic intermediate that combines the dynamic reversible cross-linking properties of the ortho-pyridyl disulfide bond (OPSS) with the high-efficiency coupling activity of N-hydroxysuccinimide ester (NHS). It is suitable for applications in the fields of biomolecule modification, nanomaterial synthesis, and catalyst loading. Its polyethylene glycol (PEG) chain can significantly improve water solubility and biocompatibility, making it an ideal choice for constructing stable composite systems.

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

III. [Application Areas]
    1. Directional coupling of proteins or polypeptides to nanoparticles (e.g., surface functionalization of gold nanoparticles).
    2. Preparation of dynamic covalent cross-linked hydrogels (utilizing the thiol reversible reaction of OPSS).
    3. Immobilization of probe molecules in biosensors (through the specific binding of NHS to amino groups).
    4. Construction of drug carrier systems (PEG enhances stability, and OPSS controls release).
    5. Surface modification of polymer materials (e.g., medical device coatings).
