I. [Product Description]
HSA-PEG-OPSS is a multifunctional organic intermediate, which is precisely coupled by human serum albumin (HSA) with the active group of ortho-pyridyl disulfide (OPSS) through a polyethylene glycol (PEG) chain. This compound combines biocompatibility and controllable reaction characteristics, and can be used as an efficient catalyst or cross-linking agent for the construction of complex molecular systems. Its PEG modification significantly improves water solubility and spatial stability.
