    Glycosylation Site and Glycan Analysis Service

      Glycosylation stands out as one of the key post-translational modifications of proteins, crucial for cellular functions and regulatory mechanisms that influence organismal growth and development. Research indicates that over half of mammalian proteins are glycoproteins, pervasive across diverse cells and tissues. Glycans exhibit considerable structural diversity, including varied branching, linkages, and configurations, imparting a broad range of biological functions vital for health, development, and survival. In the context of disease, alterations in glycosylation patterns are often closely linked to pathological conditions, offering avenues for early diagnosis and therapeutic interventions.

       

      Services at MtoZ Biolabs

      At MtoZ Biolabs, we leverage sophisticated liquid chromatography-tandem mass spectrometry (LC-MS/MS) techniques for precise analysis of glycosylation sites and their glycan profiles. Our expert team employs targeted enzymatic methods to ensure comprehensive coverage of the protein sequence, enabling accurate identification and analysis of glycosylation sites. We further enhance peptide fragment resolution using cutting-edge fragmentation technologies such as ETD, HCD, and CID, ensuring detailed and accurate analyses.
