Perfect Glycan Microarray Analysis: Experience the Precision

Glycan microarrays are powerful tools for researching the functions and roles of glycans in organisms. Previously, CD BioGlyco has established a powerful Glycobiology Microarray Platform to provide clients with different kinds of comprehensive microarray analysis services. At present, CD BioGlyco has further constructed a Glycan Display Platform on top of this platform to provide clients with a full range of glycan microarray assay services.

• Construction of glycan microarrays
  CD BioGlyco provides glycan microarray constructs that include but are not limited to, the following.
  • Covalently linked mono- (di-) glycan microarrays
    Glycan microarrays are formed by immobilizing mono- (di-) glycans by covalent linkage on a glass sheet carrier encapsulated with a monolayer of activating groups. We usually use fluorescent dyes to label and detect the binding specificity of the mono- (di-) glycan probes.
  • Non-covalently adsorbed polysaccharide microarrays
    Polysaccharides or glycoproteins are immobilized by non-covalent adsorption on a surface hydrophobic carrier. The carriers we offer contain nitrocellulose membranes and polystyrene membranes.
  • Oligosaccharide microarrays
    First, we immobilize long-chain aliphatic alkyne on the surface of solid-phase carriers by noncovalent adsorption. Second, the oligosaccharides are immobilized using cyclization-addition reactions to construct oligosaccharide microarrays.

• Based on the multiple glycan microarrays constructed, we provide detection services that include but are not limited to:

Workflow

• Sample processing and labeling

Glycan microarray assays are suitable for many types of samples (glycan-binding proteins, antibodies, cells, tissues, viruses, etc.). Depending on the type of sample, we perform initial processing, followed by fluorescent or other labeling of the biomolecules to be detected.

• Microarray hybridization and washing

The labeled samples are incubated with the glycan microarrays to allow specific binding of the molecules to be detected to the glycans. The temperature, incubation time, and buffer conditions are strictly controlled to ensure optimal binding. At the end of hybridization, unbound samples and non-specifically bound material are removed.

• Data analysis

A high-resolution microarray scanner is used to scan the chip after hybridization to obtain signal intensity data. Afterwards, we use professional bioinformatics software to process and analyze the raw data, including quantification, differential binding analysis, and cluster analysis.

Applications

• Glycan microarrays can be used to rapidly analyze the glycan binding properties of proteins, including plant and animal lectins, antibodies, and growth factors.
• Glycan microarrays can be used to probe the binding properties of pathogen glycans.
• Glycan microarrays can be used to determine the affinity glycans of quantitatively bound proteins.

Advantages

• We have a professional R&D team with in-depth research and rich experience in the construction and application of glycan microarray.
• We provide custom glycan microarray assay services according to the client's requirements. Including the construction method of glycan microarray, the type of solid phase carrier, and so on.
• Every solution we provide has gone through strict quality testing to ensure client satisfaction.
