I. [Product Description] 
HSA-PEG-Tryptophan is a multifunctional bioconjugate prepared by precise coupling technology. It combines the biocompatibility of human serum albumin (HSA) with the steric hindrance effect of polyethylene glycol (PEG). It can serve as an efficient organic intermediate and a catalyst for bioconjugation reactions. Its unique tryptophan modification group significantly enhances the molecular recognition ability and shows excellent directional coupling efficiency in complex reaction systems.
