I. [Product Introduction]
Casein-PEG-SH is a multifunctional organic intermediate. By covalently bonding casein with polyethylene glycol (PEG) and modifying the terminal with a thiol group, its water solubility and biocompatibility are significantly improved. This compound can serve as an efficient catalyst carrier or a functionalization platform and has important application value in the fields of bioconjugation and material surface modification.
