Anti-Cysteine Sulfenic Acid (2-Thiodimedone) Antibody

This rabbit IgG polyclonal antibody was generated against a linear peptide corresponding to sulfenic acid modified proteins and recognizes dimedone-modified cysteine sulfenic acid formation in cells.


  • Specific for dimedone-tagged sulfenic acid containing proteins
  • Offers immunochemical method for detecting sulfenic acid
  • Suitable for Western Blot and Immunofluorescence applications

The oxidation of cysteine to the sulfenic acid is often transient and difficult to detect, thus making it problematic in understanding the role that this oxidative post-translational modification plays in redox-biology and pathogenesis. This antibody was developed to detect hydrogen peroxide mediated thiol oxidation to sulfenic acid. The antibody is exquisitely specific, context-independent and capable of visualizing dimedone-modified cysteine sulfenic acid in cells.
