SUMOylated Peptide Detection Service

MtoZ Biolabs provides SUMOylated peptide detection service based on high-resolution mass spectrometry and specific enrichment strategies. This service helps researchers comprehensively identify and quantify SUMO modification sites on proteins, enabling a deeper understanding of their roles in signal transduction, stress response, DNA repair, and disease development. The service covers cell, tissue, and recombinant protein samples, providing reliable experimental data and technical support for post-translational modification studies.  

 

What is SUMOylation  

SUMOylation (Small Ubiquitin-like Modifier modification) is an important reversible post-translational modification. It covalently attaches SUMO proteins to lysine residues on target proteins to regulate their structure, activity, and localization. This modification is closely associated with cell cycle regulation, gene expression, protein stability, and stress response.

Abnormal SUMOylation is related to various diseases, including neurodegenerative disorders, cardiovascular diseases, and cancers. Therefore, accurate detection of SUMOylated peptides is of great significance in biomedical research.  

 

SUMOylated Peptide Detection Service at MtoZ Biolabs  

The SUMOylated peptide detection service at MtoZ Biolabs combines mass spectrometry analysis with specific enrichment strategies to accurately identify SUMO modifications in complex biological samples. We provide, but are not limited to, the following services:  

1. Identification of SUMOylated Peptides  

High-resolution LC-MS/MS systems, including Orbitrap Fusion Lumos and Q Exactive HF, are used with database searching to accurately identify SUMOylated peptides. Modification sites and the types of amino acid residues linked to SUMO can be determined.  

 

2. Quantitative Analysis of SUMOylation Levels  

Using various quantitative strategies such as Label-free, TMT, or iTRAQ, the SUMOylation levels under different treatments or biological conditions can be compared to reveal dynamic protein regulation.  

 

3. SUMO Enrichment and Selective Capture  

Anti-SUMO antibody immunoprecipitation (IP) or Ni-NTA affinity capture techniques are used to increase detection sensitivity, which is particularly effective for low-abundance proteins or complex samples.  

 

4. Customizable Analysis Plans  

Flexible experimental designs are available to meet diverse research needs, including single-protein SUMOylation studies, global SUMO proteome profiling, and multi-omics integration, supporting mechanism studies and drug screening.
