Tag His-tag
Predicted MW 52.5 kDa
Concentration lot specific
Purity >95% by SDS - PAGE
Presentation Purified
Buffer Presentation State: Purified
State: Liquid purified protein
Buffer System: 20 mM Tris-HCl buffer (pH 8.0) containing 10% glycerol, 0.1 M NaCl
Bioactivity Biological: Specific activity is < 1 unit/ml and was obtained by measuring the increase of NADP in absorbance at 340 nm resulting from the reduction of NAD.
One unit will oxidize 1.0 umole of acetaldehyde to acetic acid per minute at pH 8.0 at 25°C in the presence of beta-NAD, potassium and thiols.


Activity Assay
1. Prepare a 3 ml reaction mixture into a suitable container: The final concentrations are 103 mM Tris, 0.67 mM beta-NAD, 100 mM potassium chloride, 10 mM 2-mercaptoethanol, 2 mM acetaldehyde, 0.0007 % (w/v) BSA.
2. Equilibrate to 25°C and monitor the A340nm until the value is constant using a spectrophotometer.
3. Add 2.5 ug of recombinant ALDH3A1 into reaction mixture and mix immediately.
4. Record the increase in A340nm for 5 minutes.
Preparation Liquid purified protein
Protein Description Recombinant ALDH3A1 protein, fused to His-tag, was expressed in E.coli and purified by using conventional chromatography techniques.
Storage Store undiluted at 2-8°C for up to two weeks or (in aliquots) at -20°C or -70°C for longer.
Avoid repeated freezing and thawing.
Stability Shelf life: one year from despatch.

Summary Aldehyde dehydrogenases oxidize various aldehydes to the corresponding acids. They are involved in the detoxification of alcohol-derived acetaldehyde and in the metabolism of corticosteroids, biogenic amines, neurotransmitters, and lipid peroxidation. The enzyme encoded by this gene forms a cytoplasmic homodimer that preferentially oxidizes aromatic and medium-chain (6 carbons or more) saturated and unsaturated aldehyde substrates. It is thought to promote resistance to UV and 4-hydroxy-2-nonenal-induced oxidative damage in the cornea. The gene is located within the Smith-Magenis syndrome region on chromosome 17. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Sep 2008]
