详细描述

Can be employed for the rapid determination of D-galactose or L-arabinose. See Lactose / D-Galactose (Rapid) Assay Kit (K-LACGAR) for full details. EC 1.1.1.48 and EC 5.1.3.3, respectively. Recombinant from E. coli. These recombinant enzymes have been expressed in E. coli and purified by affinity chromatography. Electrophoretically homogeneous. In 3.2 M ammonium sulphate. Specific activity (of GalDH before mixing with mutarotase): 390 U/mg (25oC, pH 8.6, on D-galactose). Contaminants: α-galactosidase, < 0.00004 %; β-galactosidase, 0.0003 %; NADH oxidase, < 0.0003 %; alcohol dehydrogenase, trace. Stable at 4oC for > 2 years.
