A Source of Your Glycans and Glycan Derivatives

Glycans are usually attached to lipids and proteins to form glycolipid and glycoproteins. It is involved in a variety of biological process including immunological response, cell-cell communication, and inflammation reaction. Hence it is very important to synthesize glycans with high-purity to investigate glycobiology. With extensive experience in glycan synthesis, Creative Biolabs offers a full range of custom glycan synthesis services with the highest quality and the most competitive price.

Background of Glycan Synthesis

Glycans are defined as the compounds consisting of a large number of monosaccharides linked glycosidically. Usually, they are found to attach to proteins and sphingolipids in biological systems and are involved in important functions such as inflammation, the immunological response, metastasis, and bacterial and viral infection. Due to the inherent chemical properties of oligosaccharides, glycan synthesis is more complex than the other major classes of biomolecules such as proteins and nucleic acids. In biological synthesis systems, glycans are heterogeneous and their synthesis is no-template while proteins and nucleic acids are produced in homogeneous forms based on the template strand. Chemical synthesis of specific complex oligosaccharide structures that are not easily isolated from natural material or accessible via enzymatic routes usually involves a considerable number of synthetic steps.

Custom Glycan Synthesis Service at Creative Biolabs

Different strategies have been developed to make custom glycan synthesis possible, such as chemical synthesis method and chemoenzymatic synthesis. In order to increase the production of glycan, chemical synthesis method has been used to produce homogeneous glycans in larger quantities than are available from most cellular production systems. Besides, enzymes can be combined with chemical methods to further simplify the synthesis process of glycan. Moreover, chemical synthesis can be further used to incorporate polysaccharides into homogeneous glycoproteins.

Based on various synthesis strategies, Creative Biolabs offers our clients comprehensive services for custom glycan synthesis, including but not limited to:


  • Glycans with chemical modifications
  • Glycans with stable isotope labeling, such as 2H, 13C, 15N, or 18O
