Sulfated polysaccharide from Cyclocarya paliurus enhances the immunomodulatory activity of macrophages

In this study, a sulfated polysaccharide (S-CP1-8) was obtained from Cyclocarya paliurus by chlorosulfonic acid-pyridine method. S-CP1-8 was chemical characterized and cultured with macrophage RAW264.7 cells to evaluate its immunomodulatory activity. Preliminary physicochemical analysis identified arabinose (Ara), galactose (Gal) and glucose (Glc) were the major monosaccharides of S-CP1-8, with average Molecular weight (Mw) of 970 kDa and...
