What is Glycobiology Microarray?
A Glycobiology Microarray is a high-throughput screening platform used to study the interactions between carbohydrates (glycans) and other biomolecules, such as proteins, antibodies, or lectins. It allows researchers to immobilize a variety of glycans onto a solid surface in a spatially defined manner, creating an array of different glycans.
These microarrays enable the systematic investigation of carbohydrate-protein interactions, which are important for various biological processes such as cell adhesion, signaling, and immune response. By probing the microarray with different proteins or other molecules, researchers can identify specific interactions between glycans and their binding partners.
Glycobiology microarrays have applications in drug discovery, diagnostics, and basic research, providing insights into the roles of glycans in health and disease. They offer a powerful tool for characterizing glycan-binding proteins, elucidating glycan-mediated biological pathways, and developing new therapeutic agents targeting carbohydrate-protein interactions.
