DYn-2-d6 Sulfenic Acid Probe

DYn-2-d6 is a deuterated version of DYn-2, a chemoselective probe for detecting sulfenylated proteins in intact cells.

Highlights:

  • Consists of 1,3-cyclohexanedione coupled to an alkyne moiety by a fully deuterated 3-carbon spacer
  • Cyclohexanedione group selectively reacts with protein sulfenic acid modifications
  • Alkyne group of DYn-2-d6 can be detected using azide-bearing tags by standard click chemistry
  • Can be used with non-deuterated analog DYn-2 (which differs in MW by 6 Da) for quantitative analysis of cells stimulated with ROS

Mild oxidation can convert the sulfhydryl group of cysteine residues on proteins to cysteine-sulfenic acid derivatives (Cys-SOH). Protein sulfenylation is a post-translational modification that is relevant to redox signaling. DYn-2 and DYn-2-d6 differ in molecular weight by 6 Da. and can be used for quantitative analysis of cells stimulated with reactive oxygen species.
