HyNic-PEG3-TCO

HyNic-PEG3-TCO is frequently used for the selective labeling and modification of biomolecules such as proteins, peptides, or nucleic acids. The HyNic group provides a specific site for covalent attachment to aldehyde or ketone-containing biomolecules, while the PEG spacer enhances solubility and biocompatibility. The TCO group allows for subsequent bioorthogonal reactions with tetrazines, enabling specific and rapid labeling or modification of target molecules.
