商品说明:
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
Kit size:                            100 assays
