Buffer before Lyophilization Tris/PBS-based buffer, 6% Trehalose, pH 8.0
Reconstitution 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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
and FAQs
Protein FAQs
Storage Condition Store at -20°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 Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Q&A and Customer Reviews


Regarding your protein CSB-CF022654HU, could you please advise on the lead time, the sequencing, the pricing, and the expected tag information?
Also, how long after the expression begins would you know what kind of tag this protein is ultimately going to have?
Lastly, what is the expected purity?

Very nice to receive your inquiry.
Expression Region: 1-254 aa; Full length.
Tag information:Tag type will be determined during the manufacturing process. (The expected tag is N-terminal 10xHis-tagged)


The expected tag of CSB-CF022654HU is N-terminal 10xHis-tagged, if you have any special requirement for the tag, you can communicate with us in advance.
Generally, the tag of this protein can be confirmed in 15-20 working days after we receive your order.
Regarding the purity, the minimum purity that we can guarantee is 85%, which means that the purity of final protein will be above 85%.
If the customer requires much higher purity than 85%, pls remark this requirement in the order, we can try our best, but as we have never expressed, so we can't guarantee it can reach 90% or 95%.
