I. [Product Description] 
    SH-PEG-LA (Thiol-Polyethylene Glycol-Iodoacetate) is a multifunctional organic intermediate with both high coupling ability and excellent water solubility. It is widely used in protein modification, polymer material synthesis, and nanocarrier construction. The thiol group (-SH) and iodoacetyl group (-IA) in its structure can participate in click chemical reactions in a directional manner, while the PEG segment endows the molecule with good biocompatibility. It is a key catalyst and linker in the development of drug delivery systems and biosensors.

II. [Product Details] 
    【Appearance】 Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid. 
    【Stability】 Store under refrigeration and avoid repeated freezing and thawing. 
    【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 open the package for use only after constant temperature drying! 

III. [Application Fields] 
    1. Surface functionalization modification of nanomaterials (based on the thiol-metal coordination effect) 
    2. Site-specific coupling of proteins/antibodies (specific reaction between iodoacetyl group and thiol group) 
    3. Synthesis of amphiphilic block copolymers (the PEG segment regulates the hydrophilic-hydrophobic balance) 
    4. Construction of biosensor probes (enhances the loading efficiency of signal molecules) 
    5. Polymer crosslinking agent (design of controllable crosslinking degree and degradability)
