Product overview
Recombinant Human VEGF R2/KDR Protein is expressed in HEK293 cells with an mFc (IgG1) tag at the C-terminus. It contains amino acid residues Ala20-Glu764 (UniProt accession: P35968-1).
Product Details
- Molecular Aliases
- CD309; KDR; VEGFR; VEGFR2; VEGFR-21; FLK1; KRD1; Ly73;VEGFR21
- Protein Length
- Ala20-Glu764
- Expression System
- HEK293
- Theoretical Molecular Weight
- The protein has a predicted MW of 110 kDa. Due to glycosylation, the protein migrates to 150-200 kDa based on Bis-Tris PAGE result.
- Purity
- > 95% as determined by Bis-Tris PAGE > 90% as determined by HPLC
- Endotoxin
- Less than 1 EU per μg by the LAL method.
- Buffer / Formulation
- Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
- State
- Lyophilized
- Storage Conditions
- -20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
- Reconstitution Advice
- Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

Background
The vascular endothelial growth factor receptor-2 (VEGFR-2/KDR/flk-1) functions as the primary mediator of vascular endothelial growth factor activation in endothelial cells. Regulation of VEGFR-2 expression appears critical in mitogenesis, differentiation, and angiogenesis. Transcriptional regulation of the VEGFR-2 is complex and may involve multiple putative upstream regulatory elements including E boxes.
