Protein Nitration Analysis

Post-translational modifications (PTMs) are key mechanisms that regulate cellular function and signal transduction pathways. Protein nitration is a prevalent oxidative modification, typically occurring on tyrosine residues to form 3-nitrotyrosine. This process is mediated by reactive nitrogen species, such as peroxynitrite, particularly under conditions of oxidative stress. Nitration can induce significant changes in protein structure and function, thereby influencing cellular signaling, gene expression, protein-protein interactions, and metabolic processes. Recent studies have revealed that protein nitration plays a crucial role in the pathophysiology of various diseases, including cardiovascular disorders, neurodegenerative conditions, inflammatory responses, and cancer, where it has emerged as a potential biomarker. As such, precise analysis of protein nitration is indispensable for understanding its involvement in disease mechanisms and cellular regulation.

MtoZ Biolabs offers highly sensitive and specific Protein Nitration Analysis services based on advanced liquid chromatography-tandem mass spectrometry (LC-MS/MS) technology. We provide two main services: Target Protein Nitration Analysis, which uses immune enrichment combined with LC-MS/MS to accurately identify nitration sites on specific proteins, assisting researchers in studying their roles in signal transduction and cellular stress responses. Additionally, our Nitration Proteomics service employs high-throughput mass spectrometry to systematically analyze nitration modifications across the proteome, revealing their extensive involvement in metabolic regulation and disease mechanisms.
