Medchemexpress LLC Desthiobiotin polyethyleneoxide iodoacetamide | 00-00-0 | MFCD06202009 | 97.7% | C21H38IN5O6 | 10MG
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.
