QQ交談果糖酶混合物已純化
【詳細說明】
Fructanase Mixture (purified-liquid)
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 40°C), endo-inulinase 200 U/ml (on fructan at 40°C), α-galactosidase < 0.1 U/ml (on p-nitrophenyl α-galactoside at 40°C), ?-Glucanase < 0.12 U/ml (on ?-glucan at 40°C) and pectinase < 0.40 U/ml (on pectin at 40°C).
Note: This product has been purified to remove α-galactosidase, ?-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, ?-glucanase and pectinase is 0.005%, 0.006% and 0.02%, respectively. In Fructozyme (NOVO), the contamination by α-galactosidase, ?-glucanase and pectinase is 14.2%, 0.2% and 2% respectively.
Stable at 4°C for > 4 years.
