产品描述:
提供形式:in 3.2M ammonium sulphate。
酶活定义:One Unit of galactose dehydrogenase is defined as the amount of enzyme required to produce one µmole of NADH from NAD+ per minute at pH 8.6, at 25℃。
特异性: Interconversion of the α- and β-anomeric forms of D-galactose is catalysed by β-galactose mutarotase(GMR)(α-D-Galactose ↔ β-D-Galactose)。The β-D-Galactose is oxidised by NAD+ to D-galactonic acid in the presence of β-galactose dehydrogenase (GALDH) at pH 7.5,(β-D-Galactose + NAD+ → D-galactonic acid + NADH + H+)
最佳温度:25℃
最佳pH:8.6
用于 D-半乳糖或 L-阿拉伯糖的快速测定。
