Bis-sulfone-PEG4-TCO

Bis-sulfone-PEG4-TCO is utilized for the selective and specific labeling and modification of biomolecules such as proteins, peptides, or nucleic acids. The bis-sulfone functional groups provide sites for covalent attachment, while the PEG spacer enhances solubility and biocompatibility. Meanwhile, the TCO group permits subsequent bioorthogonal reactions with tetrazines, enabling specific and rapid labeling or modification of target molecules.
