Heparin sulfate (HS) is one of the most complex classes of carbohydrates that play a key role in regulating biological processes, including growth factor interactions, virus entry, and angiogenesis by binding to a host of proteins. Indeed, glycosaminoglycans have been shown to interact with a wide range of proteins, including growth factors, metalloproteinases, chemokines, and pathogenic proteins. Elucidating the sulfation specificities of the growing number of HS-binding proteins in the genome will be critical for understanding the structure-activity relationships of glycosaminoglycans and the molecular mechanisms underlying important biological processes. Creative Biolabs is a world-leading company that can provide the best microarray products and solutions for global customers in the field of protein research.
