Cat.No. : |
ALDH2-139H |
Product Overview : |
Recombinant Human ALDH2(18-517aa) was expressed in E. coli. |
Description : |
ALDH2 (Aldehyde dehydrogenase 2 family) belongs to the aldehyde dehydrogenase family which catalyze the chemical transformation from acetaldehyde to acetic acid and is the second enzyme of the major oxidative pathway of alcohol metabolism. There are two major liver isoforms of this enzyme, cytosolic and mitochondrial, and they can be also distinguished by their electrophoretic mobilities, kinetic properties, and subcellular localizations. |
Source : |
E. coli |
Species : |
Human |
Form : |
Liquid. In 20 mM Tris-HCl buffer (pH 7.5) containing 1mM DTT, 1 mM EDTA, 10% glycerol |
Bio-activity : |
Specific activity is > 250pmol/min/ug, and was obtained by measuring the increase of NADH in absorbance at 340 nm resulting from the reduction of NAD at pH 8.0 at 25 centigrade. |
