Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Our Recombinant Rat D-amino-acid oxidase (DAAO) is an essential component in the research arena of Metabolism. The protein, encoded by the 'Dao' gene in Rat species, is integral to the metabolism of D-amino acids, and is known for its catalytic role in oxidizing D-amino acids into their corresponding keto acids. This makes it a valuable tool for understanding metabolic pathways and interactions.

The protein is expressed from E.coli, capturing the full length of the protein from amino acid 1 to 346. In order to increase its versatility in various experimental protocols, the DAAO protein is tagged on the N-terminal with a 10xHis tag and on the C-terminal with a Myc tag, aiding in its purification and detection. Our product boasts a purity greater than 85%, as determined by SDS-PAGE, reinforcing its reliability. You can choose to have the Recombinant Rat DAAO protein in a liquid or lyophilized powder form, allowing for a flexible application in different experimental setups.

Target Background

Regulates the level of the neuromodulator D-serine in the brain. Has high activity towards D-DOPA and contributes to dopamine synthesis. Could act as a detoxifying agent which removes D-amino acids accumulated during aging. Acts on a variety of D-amino acids with a preference for those having small hydrophobic side chains followed by those bearing polar, aromatic, and basic groups. Does not act on acidic amino acids.

  2. Its toxic effect on motor neurons can be mediated by expression in motor neurons and it promotes autophagy. PMID: 24138986
  3. The study showed that the operation of renal ischemia resulted in a 45.49 +/- 8.30% (n = 8) decrease in the DAAO-induced consumption of substrate, indicating a sharp decrease in renal DAAO activity following this acute renal injury. PMID: 21110210

  5. results suggest that an increase in DAO expression in parts of the brain is involved in aberrant D-amino acid metabolism, may be a potential therapeutic target for schizophrenia PMID: 19685198
  6. This result clearly revealed that DAO was indispensable for the process of chiral inversion of d-leucine. PMID: 15026304
