I. [Product Description]
TF-PEG-SG (Transferrin-Polyethylene Glycol-Succinimidyl Glutarate) is a highly efficient and multifunctional organic intermediate. It enables the controllable coupling of transferrin with reactive groups through the PEG chain and is widely used in bioconjugation reactions and the construction of catalytic systems. Its unique succinimidyl ester group can specifically bind to amino groups, providing a precise modification platform for the synthesis of pharmaceutical intermediates and the development of functional materials.
