Rhodamine-PEG-Thiol (RB-PEG-SH), MW 1K with a molecular weight of 1K, is a polyethylene glycol (PEG) derivative that contains a thiol functional group (-SH) and a rhodamine fluorescent dye.
The thiol functional group of Rhodamine-PEG-Thiol can react with other molecules through disulfide bond formation, making it an ideal tool for the development of drug delivery systems. The PEG chain provides excellent solubility and biocompatibility, while the rhodamine dye enables real-time tracking of the drug delivery process. Rhodamine-PEG-Thiol has been utilized to conjugate a variety of therapeutic agents, including proteins, peptides, and small molecules, resulting in improved drug stability, solubility, and bioavailability.
