I. [Product Description]
TF-PEG-Vinylsulfone (Transferrin-Polyethylene Glycol-Vinyl Sulfone) is a multifunctional organic intermediate. By combining the biocompatibility of transferrin with the steric stability of the PEG chain, it significantly enhances the efficiency of the compound in bioconjugation and material modification. This product can serve as an efficient pharmaceutical intermediate or catalyst carrier, suitable for the surface functionalization of proteins/nanoparticles and the construction of cross-linking systems for polymer materials.
