名称：重组人Alcohol dehydrogenase class 4 mu/sigma chain/ADH7Protein（C-6His）；
产品说明(Description) Recombinant Human Alcohol Dehydrogenase Class 4 Mu/Sigma Chain is produced by our Mammalian expression system and the target gene encoding Met1-Phe386 is expressed with a 6His tag at the C-terminus. Accession #: P40394 Known as: Alcohol Dehydrogenase Class 4 Mu/Sigma Chain; Alcohol Dehydrogenase Class IV Mu/Sigma Chain; Gastric Alcohol Dehydrogenase; Retinol Dehydrogenase; ADH7 制剂（Formulation） Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4. 质量控制（Quality Control） Purity: Greater than 95% as determined by reducing SDS-PAGE. Endotoxin: Less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test. 复溶（Reconstitution） Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 保存（Storage） Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months. 背景（Background） Alcohol dehydrogenase class 4 mu/sigma chain (ADH7) is a cytoplasm enzyme which is a member of the alcohol dehydrogenase family. The expression of this gene makes it much more abundant in the stomach than the liver, thus it differs from the other known gene family members. ADH7 may participate in the synthesis of retinoic acid, a hormone important for cellular differentiation. Medium-chain (octanol) and aromatic (m-nitrobenzaldehyde) compounds are the best substrates. Ethanol is not a good substrate but at the high ethanol concentrations reached in the digestive tract, it plays a role in the ethanol oxidation and contributes to the first pass ethanol metabolism. 电泳(SDS-PAGE) FOR RESEARCH USE ONLY
