Quantitative Analysis of Monosaccharides

Glycosylation is an indispensable part of proteomics and a very critical modification of therapeutic proteins. CD BioGlyco has advanced technology and well-trained researchers to provide customers with systematic and rigorous scientific research services of monosaccharide quantitation, we have confidence to be your essential research assistant in the field of glycobiology.


As specific glycosylation patterns are inherently linked to cellular physiology and environment, monitoring altered glycosylation levels during disease has become established as valuable means in the search for diagnostic and prognostic markers. Numerous studies also have shown that it can significantly regulate the biological activity, stability, and immunogenicity of vaccine, antibodies and many other key biomolecules and therapeutic proteins. Monosaccharide analysis is a regulatory requirement for the characterization of biopharmaceuticals in the ICH Q6B guidelines. These analyses are needed to determine the type of glycosylation (N-linked and O-linked) and the degree of glycosylation at all stages of drug development. For basic research and clinical purposes, more high-throughput and quantitative analysis methods have been developed to analyze monosaccharides. The instability of monosaccharide constituents necessitates precise sample handling, high-resolution analytical separation and sensitive detection techniques.

The developments of mass spectrometry have greatly accelerated the speed of glycomics research with improvements in its sensitivity and resolution. CD BioGlyco utilizes MS in combination with the variety of liquid phase separation techniques and fluorescence, and provides systematic methods to characterize, identify and quantify monosaccharides. The methods we provide include but are not limited to:

  • MS Ionization: matrix-assisted laser desorption/ionization (MALDI) and electrospray ionization (ESI) are the standard ionization techniques used, each with their own distinct advantages and disadvantages.
  • Label Free Quantitation: it involves the MS analysis of glycans which release from their glycopeptides or proteins, in either their native state or after derivatization.
  • Labelling Quantitation: labelling strategies have been designed to improve quantitative glycomics analysis by reducing the errors that instrument and sample matrix composition can induce in non-isotopic labelling quantitative analysis.


  • Search for diagnostic and prognostic markers
  • Proteins heterogeneity research
  • Disease pathology and progression research
  • Biopharmaceutical research
