Application

Reagent for the modification of cysteine residues in proteins.
Reagent for the modification of cysteine residues in proteins. Used in protein sequencing (including by Sanger in sequencing bovine insulin) to prevent oxidation of -SH sidechains.
Reagent for the modification of cysteine residues in proteins. Used to induce animal osteoarthritis model system, which mimics both symptoms and histopathology of the human disease.
