<p>An immunopotentiator comprising polysaccharides which are constituted of four saccharides, i.e., glucuronic acid, rhamnose, galactose and glucose at a molar ratio of glucuronic acid : rhamnose : galactose : glucose of 0 - 1.2 : 2.4 - 3.6 : 0.8 - 1.2 : 0.8 - 2.4. The immunopotentiator is excellent in immunopotentiating activity and constituted of acidic heteropolysaccharides produced by microorganisms which are superior in productivity to polysaccharides originating in basidiomycetes (krestin, lentinan, etc.).</p> |
