I. [Product Description]
TF-PEG-Biotin (Transferrin-Polyethylene Glycol-Biotin) is a multifunctional bioconjugation reagent that achieves efficient conjugation of transferrin and biotin through precise organic intermediate synthesis technology. This compound is equipped with a PEG chain with adjustable molecular weight, which significantly enhances water solubility and stability. It is suitable for the construction of targeted delivery systems and the labeling of biomolecules. As a pharmaceutical intermediate, its modular design supports customized functional expansion and has important value in the fields of biosensing and carrier development.
