Glycosaminoglycan Microarray Service

What is Glycosaminoglycan Microarray?

Glycosaminoglycans (GAGs) are essential components of the extracellular matrix and cell surfaces, playing critical roles in various biological processes such as cell signaling, inflammation, and tissue regeneration. Their interactions with proteins are pivotal in regulating these processes. Glycosaminoglycan microarray technology represents a sophisticated approach to study these interactions comprehensively and efficiently.

Principle of Glycosaminoglycan Microarray

Glycosaminoglycan microarray operates on the principle of immobilizing synthetic GAG oligosaccharides onto a solid support, such as a glass slide or a chip, in a spatially defined array format. These synthetic oligosaccharides mimic the structural diversity and sulfation patterns found in natural GAGs. By immobilizing these molecules, researchers can systematically screen their interactions with proteins or other biomolecules in a high-throughput manner.
