I. [Product Description]
HSA-PEG-PEI is a multifunctional organic intermediate prepared by the precise coupling of human serum albumin (HSA) with polyethylene glycol (PEG) and polyethylenimine (PEI). This complex combines the biocompatibility of HSA, the stealth property of PEG, and the high-efficiency loading capacity of PEI. It can be used as a pharmaceutical intermediate for the modification of biomaterials or the construction of catalyst carriers.
