PFB-mercaptopropionyl-PEG3-N3 is a multifunctional linker designed for site-selective cysteine conjugation via π-Clamp-mediated chemistry. It combines a perfluorobiphenyl (PFB) group for π-π stacking interactions, a mercaptopropionyl moiety for thiol-reactive coupling, a PEG3 spacer for enhanced solubility and flexibility, and an azide (N3) group for click chemistry applications. This structure enables precise modification of peptides or proteins at specific sites, facilitating applications in bioconjugation, peptide macrocyclization, and biomolecule labeling.
