US Patent 7449452 Method for estimating immunostimulant activity of a polysaccharide

The ability of a polysaccharide to act as an immunostimulant may be assessed by comparing the degree of binding of a detection reagent, which contains a fluorescence-labeled version of the polysaccharide, with the binding of a reference reagent, which contains a fluorescence-labeled version of a different polysaccharide. The ability of a polysaccharide to act as an immunostimulant may also be assessed by comparing the degree of binding of a detection reagent, which contains a fluorescence-labeled version of the polysaccharide, with the binding of a different type of reference reagent, which contains both the same fluorescence-labeled version of the polysaccharide and an unlabelled version of the same polysaccharide.
