I. [Product Description]
TF-PEG-Rhodamine B (RB), Transferrin-Polyethylene Glycol-Rhodamine B, is a multifunctional organic intermediate. Through the precise coupling of transferrin with polyethylene glycol (PEG) and the fluorescent labeling of Rhodamine B, it combines biological targeting, water solubility, and visual tracking functions. This compound can serve as a core material for pharmaceutical intermediates or biological labeling research. The PEG modification can effectively improve the molecular stability and in vivo circulation time, making it suitable for the construction of targeted carriers and the development of in vitro analysis systems.
