Glycosylation and Related Modifications Analysis Service
MtoZ Biolabs provides Glycosylation and Related Modifications Analysis Service to support precise identification and quantification of glycosylation and its associated protein modifications. By combining optimized enrichment techniques with advanced LC-MS/MS workflows, we deliver comprehensive datasets that capture both the diversity and the dynamics of glycan modifications. Our Glycosylation and Related Modifications Analysis Service integrates multiple quantification strategies, including TMT, iTRAQ, and label-free methods, enabling reliable cross-sample comparison as well as scalable analysis for large cohorts. These capabilities provide researchers with actionable insights into the roles of glycosylation and related modifications in cellular function and disease progression.
What is Glycosylation and Related Modifications?
Glycosylation is one of the most widespread and complex post-translational modifications, involving the covalent attachment of glycans to proteins or lipids. It profoundly influences protein folding, stability, trafficking, and interactions, and it plays essential roles in immunity, signaling, and cell–cell communication.
In addition to classical N-linked and O-linked glycosylation, several related modifications contribute to fine-tuned protein regulation. O-GlcNAcylation is a dynamic and reversible glycosylation that modulates transcription, signal transduction, and stress responses. Glypiation, on the other hand, anchors proteins to membranes through glycosylphosphatidylinositol (GPI), impacting protein localization and cell signaling. Together, glycosylation and its related modifications shape the functional diversity of proteins and have been linked to cancer, immune dysfunction, neurodegeneration, and metabolic disorders.
