High purity Fructanase Mixture (purified-liquid) for use in research, biochemical enzyme assays and in vitro diagnostic analysis.
For Fructan Determination (Liquid).
Components: exo-inulinase 2,000 U/ml (on kestose, at 40oC), endo-inulinase 200 U/ml (on fructan at 40oC), α-galactosidase < 0.1 U/ml (on p-nitrophenyl α-galactoside at 40oC), β-Glucanase < 0.12 U/ml (on β-glucan at 40oC) and pectinase < 0.40 U/ml (on pectin at 40oC).
Note: This product has been purified to remove α-galactosidase, β-glucanase and pectinase which interfere with the use of the preparation in the measurement of fructan, or in the solubilisation of "insoluble" fructan in the AOAC Total Dietary Fiber method. In this product, the contamination of exo-inulinase by α-galactosidase, β-glucanase and pectinase is 0.005%, 0.006% and 0.02%, respectively. In Fructozyme (NOVO), the contamination by α-galactosidase, β-glucanase and pectinase is 14.2%, 0.2% and 2% respectively.
Stable at -20oC for > 4 years.
