    Detection of Protein Glycosylation Sites in Spirulina

      Spirulina is a spiral-shaped blue-green algae with a high protein content. About 60% to 70% of its dry weight is protein. It mainly grows in alkaline waters and is increasingly gaining attention in the field of health foods and medicine.


      Glycosylation is an important form of post-translational modification of proteins, affecting the folding, stability, activity, and interactions of proteins in cells. The detection of glycosylation sites in spirulina protein is helpful in understanding its biological functions and potential medicinal value. By precisely analyzing the glycosylation pattern of spirulina protein, we can optimize the production process and enhance the quality and effect of health foods and medicines. Moreover, research on the glycosylation sites of spirulina protein may also help discover new bioactive substances, providing new strategies for disease treatment.


      MtoZ Biolabs is equipped with two mass spectrometry technologies, MALDI TOF MS, and nano LC-ESI-MS/MS, to provide efficient and accurate identification of spirulina glycosylation sites. After receiving the sample, we first digest it to release the Fc domain and Fab of the antibody, then separate the glycosylated fragments, and confirm the glycosylation sites through MALDI TOF MS or nano LC-ESI-MS/MS.
