Cysteine-specific Linker

Cysteine-specific Linker


Cysteine-specific linkers are molecules used in bioconjugation to selectively attach drugs, imaging agents, or other functional moieties to cysteine residues within proteins or peptides. They contain reactive groups that target the thiol (-SH) side chain of cysteine, forming stable covalent bonds. This site-specific reactivity enables precise and stable modification of biomolecules for therapeutic, diagnostic, or research applications
