| Synonyms | Aflatoxin B1 aldehyde reductase member 2, AFAR, AFAR1, AFB1-AR1, AKR7, Succinic semialdehyde reductase, SSA reductase, AFB1 aldehyde reductase 1, Aldoketoreductase 7, AKR7A2. | ||||||
| Introduction | AKR7A2 participates in the detoxification of aldehydes and ketones. AKR7A2 catalyzes the NADPH-dependent reduction of succinic semialdehyde to gamma-hydroxybutyrate. AKR7A2 is involved in producing the neuromodulator gamma-hydroxybutyrate （GHB）. AKR7A2 has extensive substrate specificity. AKR7A2 shows NADPH-dependent aldehyde reductase activity towards 2-carboxybenzaldehyde, 2-nitrobenzaldehyde and pyridine-2-aldehyde （in vitro）. AKR7A2 reduces 1,2-naphthoquinone and 9,10-phenanthrenequinone （in vitro）. AKR7A2 reduces the dialdehyde protein-binding form of aflatoxin B1 （AFB1） to the non-binding AFB1 dialcohol. AKR7A2 takes part in protection of liver against the toxic and carcinogenic effects of AFB1, a potent hepatocarcinogen. | ||||||
| Description | AKR7A2 Human Recombinant fused to a 39 amino acid His Tag at N-terminal produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 398 amino acids （1-359 a.a） and having a molecular mass of 44 kDa. The AKR7A2 is purified by proprietary chromatographic techniques. | ||||||
| Source | Escherichia Coli. | ||||||
| Physical Appearance | Sterile Filtered clear colorless solution. | ||||||
| Formulation | The AKR7A2 solution contains 20mM Tris-HCl pH-8, 1mM DTT and 20% glycerol. | ||||||
| Stability | Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Avoid multiple freeze-thaw cycles. | ||||||
