Target Protein Sequence
Note: The complete sequence including tag
sequence, target protein sequence and linker sequence could be provided upon request.
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.
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.
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
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.
Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

The DNA fragment encoding the 20-764aa of the human KDR protein was fused with N-terminal GST tag gene and then was inserted into the expression vector, which was subsequently transformed into the E.coli for expression. The resulting product was further purified to obtain the recombinant human KDR protein. The purity of this recombinant KDR protein is greater than 90% assessed by Bandscan software analysis combined with SDS-PAGE. This KDR protein showed a band on the gel with a molecular weight of approximately 105 kDa.
As a VEGF receptor, VEGFR-2 (also known as KDR, FLK1, CD309) is a type IV receptor tyrosine kinase. It plays major part in the regulation of VEGF-induced endothelial proliferation, survival, migration, tubular morphogenesis and sprouting. In addition, KDR has been found closely related with the SHC2, Annexin A5, SHC1. The signaling involved in the KDR include Rab GTPase, P2Y purine nucleotide receptor, integrin alphaVbeta3, T-cell protein tyrosine phosphatase, etc. KDR exerts multiple biological effects through its interaction with other molecules. Of note, more researches suggested that KDR participates in the tumor growth and metastasis.
