Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.

Tag Info

N-terminal His-tagged/Tag-Free
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.

Storage

Store at -20°C, for extended storage, conserve at -20°C or -80°C.

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.

Notes

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

■ Q&A

We are interested in retinol binding protein (human) full-length. Without tags, without sodium azide and we would like it lyophilized. Can you provide this request?

Thanks for your inquiry.
1.Regarding the protein without sodium azide, there is no problem, all of our proteins don't contain any sodium azide.
2.But as for the no tag protein, we can have a try but we can't guarantee.
Please remark your requirement for tag removal if you need the untagged protein or tag removal when placing the order. We can try enzyme digestion, but we can't guarantee 100% successfully.The overall success rate of enzyme digestion data analysis is 75%-86%.
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 fees 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.
3.We can provide lyophilization service for free, lead time will be extended for 3 working days, please be noted that we will add 6% trehalose added as the protective agent during the lyophilization. Please check if this is OK for you.

Target Background

Function(From Uniprot)

Cytoplasmic retinol-binding protein. Accepts retinol from the transport protein STRA6, and thereby contributes to retinol uptake, storage and retinoid homeostasis.
