I. [Product Description]
IA-PEG-SPDP (Iodoacetate-Polyethylene Glycol-Dithiopyridine Disulfide) is a multifunctional organic intermediate with both high crosslinking efficiency and biocompatibility. Its PEG segment endows the molecule with excellent water solubility and steric hindrance effect, and the SPDP group can achieve controllable coupling through disulfide bonds. It is widely used in protein modification, nanocarrier construction, and catalytic reaction systems.
