(1-3)-β-D-glucans (BGs), found in culinary-medicinal mushrooms, exhibit an immunostimulatory effect; hence, it is important to measure the content of BGs contained in mushrooms. BGs content in a mushroom extract was measured using a recombinant BG-binding protein, supBGRP, and compared with the existing BG assay using BGs antibody. The specificity of supBGRP enzyme immunoassay (EIA) was evaluated using a commercially available polysaccharide reagent. The supBGRP did not react to barley glucan, dextran, mannan, pustulan, and xylan
