Polysaccharide is a natural macromolecular compound with complex, important and multifaceted biological activities. Some of polysaccharides have been marketed in China as drugs or healthy products. More studies confirm that the active ingredient of many traditional Chinese medicine exist in the form of polysaccharides. They play a role in disease therapy by activating immune cells and the compl...

Based on the fluorescence resonance energy transfer (FRET) and fluorescence anisotropy (FA), the present study reported proof-of-principle for a highly sensitive and rapid detection technique that can be precisely utilized for investigating the self-assembly of polydeoxyadenylic acid (poly(dA)) and β-glucan, and the interactions of the poly(dA)-β-glucan complex on the surface of graphene oxide ...

Various mitogens have been described which act on different subpopulations of mouse and/or human peripheral lymphocytes. In recent years it has been mainly Japanese and German research teams that have isolated polysaccharide fractions with immunomodulative properties [1-3, 17]. In addition to fungal polysaccharides such as lentinan, schizophyllan, and PSK polysaccharide, which are basically in ...

The polysacchande fraction from the leaves of Artemisia princeps Pamp (Japanese name = Gaiyo) showed a potent anti-complementary activity. Two major active polysaccharides (AAF-IIb-2 and IIb-3) were purified by ion exchange chromatography on DEAESepharose, affinity chromatography on Ricinus communis-agglutinin conjugated Sepharose and gel filtration on Sephadex G-100 and Sepharose CL-4B. The mo...
