For the measurement of 1,3:1,6-ß-glucan and α-glucan in yeast preparations. Content: 100 assays per kit

Colourimetric method for the determination of Yeast and 
Mushroom β-Glucan in yeast, mushroom, foodstuffs and 
other materials

Principle:
                                                              (conc. HCl, 30°C, 45 min)
(1) 1,3:1,6-β-Glucan + 1,3-β-glucan + α-glucan + H₂O → 
                                                                        soluble glucan

                         (1.3 M HCl, 100°C, 2 h)
(2) Soluble glucan + H₂O → D-glucose + laminarisaccharides (trace)

                  (exo-1,3-β-glucanase + β-glucosidase)
(3) Laminarisaccharides + H₂O → D-glucose

                              (glucose oxidase)
(4) D-Glucose + H₂O + O₂ → D-gluconate + H₂O₂

                                                                                (peroxidase)
(5) 2H₂O₂ + p-hydroxybenzoic acid + 4-aminoantipyrine → 
                                                                        quinoneimine + 4H₂O

                       (amyloglucosidase)
(6) α-Glucan + H₂O    →    D-glucose
