Biotinylated Human VEGF R2 / KDR Protein, Avi Tag (Avitag™)

  • Synonym
    KDR,CD309,FLK1,VEGFR,VEGFR2
  • Source
    Biotinylated Human VEGF R2, His Tag (KDR-H82E5) is expressed from human 293 cells (HEK293). It contains AA Ala 20 - Glu 764 (Accession # AAI31823).
    Predicted N-terminus: Ala 20
  • Molecular Characterization
    VEGF R2(Ala 20 - Glu 764) AAI31823

    This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag.

    The protein has a calculated MW of 86 kDa. The protein migrates as 120-130 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Biotinylation
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    No activity loss is observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.

Immobilized Human VEGF165, Tag Free (Cat. No. VE5-H4210) at 2 μg/mL (100 μL/well) can bind Biotinylated Human VEGF R2, His Tag (Cat. No. KDR-H82E5) with a linear range of 0.15-2.5 μg/mL (QC tested).

  • Background
    Kinase insert domain receptor (KDR) is also known as CD309, FLK1, VEGFR, VEGFR2, and is one of the subtypes of VEGFR. VEGF receptors are receptors for vascular endothelial growth factor (VEGF). There are three main subtypes of VEGFR, numbered 1, 2 and 3. The VEGF receptors have an extracellular portion consisting of 7 immunoglobulin-like domains, a single transmembrane spanning region and an intracellular portion containing a split tyrosine-kinase domain. VEGF-A binds to VEGFR-1 (Flt-1) and VEGFR-2 (KDR/Flk-1). VEGFR-2 appears to mediate almost all of the known cellular responses to VEGF.The function of VEGFR-1 is less well defined, although it is thought to modulate VEGFR-2 signaling. Another function of VEGFR-1 may be to act as a dummy/decoy receptor, sequestering VEGF from VEGFR-2 binding (this appears to be particularly important during vasculogenesis in the embryo). In addition, VEGFR2 is able to interact with HIV-1 extracellular Tat protein upon VEGF activation, and seems to enhance angiogenesis in Kaposi's sarcoma lesions.
