WebAug 26, 2024 · Activated Thiol Sepharose (ATS), which contains a dipyridyl disulfide group that can bind to free thiol–containing proteins ( 23 ), is another promising redox probe. The disulfide bond formed between ATS and free thiols is both strong and reversible, enabling harsh purification conditions followed by easy, quantitative elution for MS analysis.
