Form Liquid or Lyophilized powder
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.
Buffer 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.
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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

Q&A and Customer Reviews


I am interested in several of your recombinant proteins. Can you please provide some informations:
For CSB-EP011930HU (all expression systems):
b.Tag type
c.Tag position
d.Sizes and formats
e.Is the protein provided soluble in solution?
f.Is the protein purified from bacterial inclusion bodies are you supplied refolded or still in urea?
g.I want to use this protein for conjugation purposes and need it supplied in an amine free buffer (so not Tris). Can you supply this protein in one of the buffers at my request: phosphate, carbonate, or borate? Would there be an extra charge?

Thanks for your inquiry. Proteins will be supplied soluble in solution.
It is not certain for the protein to be expressed in the supernatant or precipitation, but our proteins are provided with folding correctly.
If you need it supplied in an amine free buffer (so not Tris). We can do this. Please mention this requirement in your official order. We can try to provide PBS buffer, this is not extra charged.

Target Data

Function Tyrosine kinase of the non-receptor type, involved in the IFN-alpha/beta/gamma signal pathway
Subcellular Location Endomembrane system, Peripheral membrane protein
Protein Families Protein kinase superfamily, Tyr protein kinase family, JAK subfamily
Tissue Specificity Expressed at higher levels in primary colon tumors than in normal colon tissue. The expression level in metastatic colon tumors is comparable to the expression level in normal colon tissue.
