    How to Detect Abnormal Glycoproteins

      Glycoproteins (also known as sugar chains) are a class of molecules that carry one or more sugar chains on their protein structures. The structure and composition of these sugar chains play a key role in many biological processes, including cell recognition, signal transduction, and immune responses. In certain disease states, such as cancer, autoimmune diseases, and genetic diseases, the structure of sugar chains may change. Therefore, detecting these changes is crucial for disease diagnosis and research abnormalities.


      Services at Mtoz Biolabs

      1. Mass Spectrometry (MS)

      (1) It uses a mass spectrometer to analyze protein samples to identify glycosylation sites and their glycan structures.

      (2) By comparing samples from disease states and healthy states, abnormal glycan patterns can be identified.


      2. High-Performance Liquid Chromatography (HPLC)

      (1) It is used to separate and identify sugar chains.

      (2) It can be used in conjunction with mass spectrometry to provide more detailed information on glycan structures.


      3. Western Blotting Using Specific Antibodies

      (1) It uses specific antibodies to detect proteins with specific sugar-type structures.

      (2) This method is particularly effective for abnormal glycoproteins with known specific sugar-type structures.


      4. Enzyme-Linked Immunosorbent Assay (ELISA)

      (1) It uses specific antibodies to detect glycoproteins.

      (2) It is suitable for rapid screening and quantitative analysis.


      5. Flow Cytometry

      (1) It is used to analyze glycoproteins on the cell surface.

      (2) It is particularly suitable for live cell analysis.


      6. Capillary Electrophoresis

      (1) It is used for the separation and analysis of the sugar chains of proteins.

      (2) It provides high-resolution and high-sensitivity analysis.


      7. Bioinformatics Analysis

      (1) It uses computational methods to analyze and compare glycan data.

      (2) It helps to discover disease-related abnormal glycan patterns.


      8. Nuclear Magnetic Resonance (NMR) Spectroscopy Analysis

      (1) It provides detailed information on glycan structure.

      (2) It is suitable for the analysis of complex glycan structures.
