Venom N-Glycan Qualitative Analysis Service
Venom glycosylation not only affects the folding, stability, immune evasion, and biological activity of venom proteins, but also determines their binding specificity with receptors. In particular, N-glycosylation is widely present in various venom sources such as snake venom, spider venom, and insect venom, and plays a key role in toxin structural stability, toxic activity, and evolutionary diversity.
With the advancement of mass spectrometry technology, venom N-glycan qualitative analysis has become an effective approach to reveal the molecular characteristics, structural heterogeneity, and biological functional mechanisms of venom proteins. Relying on advanced mass spectrometry platforms and extensive proteomics experience, MtoZ Biolabs provides high-quality and reproducible Venom N-Glycan Qualitative Analysis Service that helps clients comprehensively analyze venom protein glycan compositions and provides solid data support for functional studies, toxicological analysis, and drug development.

Analysis Workflow
1. Sample Pretreatment and Protein Extraction: Tailored gentle extraction and purification methods are employed to preserve the integrity of glycan structures in complex venom samples.
2. N-Glycan Release and Purification: Enzymatic (e.g., PNGase F) or chemical approaches efficiently release N-glycans, followed by solid-phase extraction or multi-step desalting to remove impurities.
3. Derivatization and Detection Optimization: Appropriate derivatization strategies (such as reductive amination or methylation) are selected to improve glycan ionization efficiency and detection sensitivity.
4. High-Resolution LC–MS Detection: High-resolution liquid chromatography–mass spectrometry systems are used to characterize glycan structures and generate qualitative glycomics data through spectral matching.
5. Data Analysis and Reporting: Professional bioinformatics tools are applied for glycan identification, structural annotation, and qualitative reporting, producing results directly applicable to subsequent studies.
Service Advantages
1. Complex Sample Analysis
Venom samples often contain diverse high-molecular-weight toxins and protein impurities. With rich experience in complex matrix sample handling, MtoZ Biolabs applies multi-step purification and customized pretreatment workflows to ensure complete glycan release and high-sensitivity detection, guaranteeing accurate and reproducible results.
