Abstract

Chondroitin sulfate (CS) is a linear heteropolysaccharide of repeating disaccharide units bearing sulfate groups in various positions, commonly at C4 and/or C6 of galactosamine. CS plays important roles in various (patho)physiological processes also performing intriguing biological and therapeutical activities. Plasmatic CS is mainly composed of nonsulfated and 4-sulfated disaccharides. To obtain samples for the determination of CS amount and composition in blood/plasma, dried blood spot (DBS) could be used. DBSs have many advantages over other laboratory methods, allowing for large-scale population screening. Many analytical techniques may be used for the determination of CS. In particular, CE has proved to be a very attractive alternative separation technique for complex polysaccharide characterization. In this work, we compared CS levels between plasma and DBS samples, using CE equipped with the highly sensitive laser-induced fluorescence detector. CS from DBS differs from plasma CS owing to the high content of disaccharides sulfated in C4 and C6. This is due to the presence of the more sulfated CS derived from blood cellular fraction, in particular leukocytes. The identification and quantification of CS in blood plasma could be a useful prognostic and diagnostic tool in pathological conditions and for pharmacological applications.
