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

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

■ Q&A

Can you please provide the following:
1)For catalog: CSB-EP001858HU (all expression systems):
a.Has the tag been removed successfully for any expression systems? If yes, which ones?; b.Do you have any metabolism studies related data? Or knowledge on using this protein in metabolism studies? What co-factors are involved? What positive control can I use? (I don’t expect you to know this Vivian but thought I’d ask just in case you may.)
2)I am also looking for the following isoforms you may have, 2,3,4,etc. :
a.Recombinant Human Aldehyde oxidase 2 (full-length); b.Recombinant Human Aldehyde oxidase 3 (full-length); c.Recombinant Human Aldehyde oxidase 4 (full-length)
If you have these proteins, can you please also provide the same information requested above for AO a.Sequence; b.Tag type; c.Tag position; d.Sizes and formats; e.Has the tag been removed successfully for any expression systems? If yes, which ones?; f.Do you have any metabolism studies related data?...

Thanks for your inquiry.

Sorry, we have never removed the tag of this protein before, We can try enzyme digestion, but we can't guarantee 100% successfully.
The overall success rate of enzyme digestion data analysis is 75%-86%, but we should explaing to you in advance:
Not all protein tags can be removed as some proteins will be very unstable after tag removal.
If we succeed in removing the tag, we will charge for extra cost.
If we fail in removing the tag, we won’t charge for tag removal and provide the fusion protein, and remark this information in datasheet as follows “Note: The laboratory determined that the Tag on your protein could not be removed with standard laboratory procedures. Your protein is being supplied with the Tag intact.”
Generally, the delivery time will be extended for 3 days.
Please refer to the following link, it have the information of the metabolism studies: http://dmd.aspetjournals.org/content/38/8/1322.long
About the Aldehyde oxidase, the human species only express AOX1, so we don't have 2,3,4.

Target Background

Function

Oxidase with broad substrate specificity, oxidizing aromatic azaheterocycles, such as N1-methylnicotinamide, N-methylphthalazinium and phthalazine, as well as aldehydes, such as benzaldehyde, retinal, pyridoxal, and vanillin. Plays a key role in the metabolism of xenobiotics and drugs containing aromatic azaheterocyclic substituents. Participates in the bioactivation of prodrugs such as famciclovir, catalyzing the oxidation step from 6-deoxypenciclovir to penciclovir, which is a potent antiviral agent. Is probably involved in the regulation of reactive oxygen species homeostasis. May be a prominent source of superoxide generation via the one-electron reduction of molecular oxygen. Also may catalyze nitric oxide (NO) production via the reduction of nitrite to NO with NADH or aldehyde as electron donor. May play a role in adipogenesis.
