MtoZ Biolabs provides Nitrosylation Proteomics Analysis Service to identify and quantify protein S-nitrosylation in complex biological samples. By combining controlled sample handling, selective enrichment chemistries, and high-resolution LC-MS analysis, we deliver site-resolved evidence for nitrosylation and decision-ready outputs for redox signaling, disease mechanism, and drug response studies.
Nitrosylation Proteomics Analysis Service at MtoZ Biolabs
Protein nitrosylation most commonly refers to S-nitrosylation, a reversible modification in which a nitric oxide group is added to a cysteine thiol to form an S-nitrosothiol. Because S-nitrosylation is often low abundance and chemically labile, analytical workflows typically emphasize selective labeling, protection of thiols from artifactual oxidation, and enrichment of modified cysteine-containing peptides prior to mass spectrometry.
MtoZ Biolabs provides an end-to-end nitrosylation proteomics workflow that integrates optimized sample handling, selective chemistry for S-nitrosylation capture, affinity enrichment, and high-resolution LC-MS/MS analysis. We tailor labeling and enrichment conditions to your sample matrix and project goal, enabling both discovery-style profiling and comparative analysis across study groups. Deliverables are structured for practical interpretation, including site tables, protein summaries, and QC documentation aligned with your experimental design.
