Chemists at Biothera, the manufacturer of Wellmune WGP and other yeast beta 1,3/1,6 glucan ingredients, developed the Glucan Enzymatic Method (GEM) as a solution to shortcomings of traditional glucan assays.
Methods employing acid hydrolysis, for example, break down the beta glucan and all other polysaccharides present into glucose. The inability to distinguish between polysaccharides often results in an overestimation of the actual beta glucan content. GEM relies upon selective enzymes that detect beta glucan and break it down to glucose while leaving other polysaccharides intact. Another application of GEM is beta glucan analysis for finished products. For further information: www.biothera.com
