Glycosaminoglycans Detection

Glycosaminoglycans (GAGs) are negatively charged polysaccharides located in most connective tissues and extracellular matrix (ECM), as well as on the surfaces of many cell types. Consisting of repeating core disaccharide units, GAGs are categorized into four types: heparin/heparan sulfate, chondroitin/dermatan sulfate, keratin sulfate and non-sulfated hyaluronan. Sulfated GAGs in the ECM exist as proteoglycan which typically consists of multiple glycosaminoglycan chains attached to a core protein. As a highly organized ECM, articular cartilage is composed of type II collagen, hyaluronan, link protein, and chondroitin sulfate-rich proteoglycans, which provide the osmotic resistance necessary for cartilage to resist compressive loads.  Chondrex provides a sulfated GAGs assay kit using the cationic dye, 1,9 dimethylmethylene blue (DMB) which binds to highly charged sulfated GAGs, not including hyaluronan. This kit utilizes an improved DMB solution minimizing interference with negatively charged contaminants, such as DNA and RNA, and chondroitin sulfate as an appropriate standard for the analysis of ECM in cartilage.
