  • Title: A high-performance liquid chromatography for constituent disaccharides of chondroitin sulfate and dermatan sulfate isomers.
    Author: Murata K, Yokoyama Y.
    Journal: Anal Biochem; 1985 May 01; 146(2):327-35. PubMed ID: 3927769.
    Abstract:
    An improved high-performance liquid chromatography for unsaturated disaccharides prepared from chondroitin sulfate and dermatan sulfate isomers was developed using an ion-exchange resin made from a sulfonized styrene-divinylbenzene copolymer. By this newly devised method, it was found that the retention times of representative unsaturated disaccharides are very unique and appear in the following order: unsaturated 6-sulfated, nonsulfated, and 4-sulfated disaccharides. The content of the individual unsaturated disaccharides could be measured at similar sensitivities with ultraviolet absorbance. Sensitive and unique retention times as well as good resolution were found for various unsaturated disulfated disaccharides. The new microassay method by HPLC can be used to determine chondroitin sulfate and dermatan sulfate isomers in amounts as small as 100 ng to 8 micrograms. The practicality of this method was verified by application to the separation and quantitation of chondroitin sulfate and dermatan sulfate isomers from human coronary arteries.
