Chondroitin/dermatan disaccharide. Sodium Salt. Chondroitin/Dermatan Sulfate Disaccharides are produced by bacterial chondroitinase digestion of Chondroitin and Dermatan sulfate. Chondroitin, a glucosaminoglycan (GAG), is a polysaccharide chain of alternating units of N-acetylgalactosamine (GalNAc) and glucuronic acid (GlcA) that can be sulfated on the either or both GalNAc and GlcA units. Chondroitin and its sulfates are frequently attached to proteins to form proteoglycans.
Chondroitin disaccharide Δdi-4S may be used as a substrate for the identification and characterization of enzymes such as Clostridium perfringens unsaturated glucuronyl hydrolase. Chondroitin disaccharide Δdi-4S may be used as a reference compound in the analysis of chondroitin disaccharide sulfates.
Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
