Glycome comparison and analysis in the context of different types of biological and chemical information is a challenge, and glycoinformatics helps to develop simplified standards for data reporting and sharing. As an industry-leading biology company, CD BioGlyco has developed the widely-used Glycoinformatics system based on its existing carbohydrate database to provide high-quality and professional Glycomics Analysis Services to clients.
The interpretation and storage of analytical data, such as liquid chromatography (LC), mass spectrometry (MS), nuclear magnetic resonance (NMR), etc., has been a focus of many advances in the development of glycome-related databases and informatics tools. CD BioGlyco provides various types of glycomic analysis skills to clients, which are combined with computational methods and machine learning technology in glycoinformatics to help clients perform adequate glycome comparison analysis.
MS is a powerful tool used to determine the sequence and structure of glycans. We analyze possible glycan compositions based on experimental mass values of free or derived glycans or glycopeptides and identify unknown structures by comparing unknown samples with MS data from databases where glycans are already stored. In addition, MS permits visualization of the distribution of glycans in various tissues and comparative analysis of glycans from different sources.
Based on the chromatographic database, we perform pattern matching of LC peak shifts of glycans in different samples for glycome comparison analysis. We offer LC technology suitable for a large range of samples such as labeled glycans, N-glycans, O-glycans, glycosphingolipids (GSL), free oligosaccharides, etc.
NMR is the best analysis technology for obtaining complete structural information on purified oligosaccharides. Currently, almost all glycan structures have been covered in the NMR database. Therefore, we utilize the NMR database to predict the 1H NMR and 13C NMR chemical shifts of target glycans to achieve the purpose of determining the structure of glycans for our clients.
We provide glycan microarray databases to our clients to help them analyze and compare the relative binding strength/specificity of various glycan-binding proteins to the glycan motifs or determinants on the arrays. In addition, we also predict glycan binding patterns with glycan microarray data.

Results: In this article, the authors analyzed the urinary N-glycome using the LC-MS/MS technique and compared it with the serum N-glycome. During the experiment, the N-glycome was released using hydrazine and labeled with 2-aminopyridine, then purified using anion exchange chromatography, and finally analyzed qualitatively and quantitatively using LC-MS/MS. The authors detected a total of 109 N-glycans. Comparisons between urine and serum N-glycome showed that approximately half of the N-glycans were of renal origin and the remaining half were common in both urine and serum. In conclusion, these research results contribute to the analysis of the human urinary N-glycome and structural analysis.
