Desthiobiotin polyethyleneoxide iodoacetamide is a cysteine-reactive labeling reagent for chemoproteomic workflows that derivatizes thiol groups for enrichment and analysis. It couples a desthiobiotin affinity tag to targets via a polyethylene oxide spacer and an iodoacetamide electrophile that alkylates cysteine residues. Supplied for research use only.

• Enables selective labeling of cysteine residues for downstream enrichment and mass spectrometry analysis.
• Includes desthiobiotin affinity tag for reversible streptavidin-based capture.
• Polyethylene oxide spacer improves solubility and reduces steric hindrance.
• Iodoacetamide electrophile provides rapid and specific thiol alkylation under mild conditions.
• Provided with reported purity suitable for proteomic applications.
