I. [Product Introduction]
TF-PEG-Lysines is a multifunctional organic intermediate based on the composite structure of transferrin-polyethylene glycol-lysine. Through precise coupling technology, it achieves a stable combination of the transferrin carrier and the PEG chain, possessing both biocompatibility and chemical modifiability. This product can serve as an efficient catalyst or pharmaceutical intermediate and is widely used in bioconjugation, nanomaterial synthesis, and targeted carrier construction. Its modular design supports customized molecular weights and functional group expansion.
