Description

Vinylsulfone-PEG-Biotin (VS-PEG-Biotin) enables site-specific modification of proteins and peptides. By reacting with cysteine residues via the vinylsulfone group, it allows for the attachment of biotin tags. It is crucial for adding functionality to proteins for immobilization, purification, or detection purposes, as well as facilitating the conjugation of proteins with other molecules, such as drugs or fluorescent probes, while preserving protein activity and structure. Vinylsulfone is a reactive group that forms covalent bonds with thiol (-SH) groups under mild conditions. In bioconjugation chemistry, vinylsulfone reacts specifically with cysteine residues or other thiol-containing molecules on biomolecules such as proteins, peptides, or nanoparticles.
