The derivatization of sialic acid is of great significance to improve the detection sensitivity or chromatographic resolution. After decades of development, CD BioGlyco has gradually established a variety of derivatization methods to meet the diverse needs of customers. We are delighted to be your scientific assistant in glycobiology.
Sialic acids are derivatives of neuraminic acid, which is a nine-carbon-containing-monosaccharide. Sialic acids are generally found at the terminal of various glycoconjugates. The evidence accumulated so far demonstrates that sialic acids actually play crucial roles in biological processes widely by affecting the chemical and biological characteristics of glycolipids and glycoproteins. In order to deeply understand the biological function of sialic acids, researchers in the field of glycomics have established a variety of characterization and analysis strategies after decades of effort.
Analytical methods based on chromatography and/or mass spectrometry are the most important and widely used methods in the analysis of sialic acids. However, it often has problems such as low detection sensitivity, easy destruction of the structure, and poor chromatographic separation during the analysis of natural sialic acids by chromatography and mass spectrometry. Therefore, sialic acid derivatization is necessary for the process of sample pretreatment, which has advantages of improving detection sensitivity, stabilizing sialic acid structure, enhancing chromatographic separation efficiency, changing fragmentation mode, and strengthening structural characteristics.
