General description

Monoclonal Anti-Vascular Endothelial Growth Factor Receptor-2 (mouse IgG1 isotype) is derived from the KDR-2 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. Vascular endothelial growth factor receptor 2 (VEGFR2) is a type V receptor tyrosine kinase, also known as kinase insert domain receptor (KDR) or fetal liver kinase 1 (Flk-1). It a glycosylated protein with an immunoglobulin (Ig)-like domains, a transmembrane domain and a tyrosine kinase domain. The KDR gene is mapped to human chromosome 4q12 and is widely expressed in all vessel-derived endothelial cells and hematopoietic stem cells.

Specificity

Reacts specifically with human VEGF receptor-2. This clone has also been termed 260.4. It does not recognize Flt1 (VEGFR-1), Flt4 (VEGFR-3), or platelet-derived growth factor receptor (PDGF-R).

Immunogen

purified recombinant human extracellular VEGF receptor-2 (KDR).

Application

Monoclonal Anti-Vascular Endothelial Growth Factor Receptor-2 (KDR) antibody produced in mouse has been used in:
  • immunofluorescence
  • immunohistochemistry
  • immunoblotting
  • enzyme-linked immunosorbent assay(ELISA)

Biochem/physiol Actions

Vascular Endothelial Growth Factor Receptor-2 (VEGF R2) have high affinity for vascular endothelial growth factor-A (VEGF-A), hence facilitates most of the endothelial growth and survival signals from VEGF-A. It also plays a pivotal role in vascular development, vascular permeability, embryonic hematopoiesis and regulation of angiogenesis.
Vascular endothelial growth factor receptor 2 (VEGFR2) or kinase insert domain receptor (KDR) is a VEGF receptor, which stimulates its mitogenic activity. It is crucial for vascular endothelial cell development. VEGFR2 expression is elevated in invasive breast cancer, hemangiomas and angiosarcomas. KDR expressing cells show striking changes in cell morphology, actin reorganization and membrane ruffling, chemotaxis, and mitogenicity in response to VEGF. Antibodies that react specifically with the VEGF receptor are useful for the study of the specific differential tissue expression and intracellular localization of the receptor in normal and neoplastic tissue.

Target description

The KDR receptor (VEGFRa), defining marker of hematopoietic stem cells (HSCs), distinguishes pluripotent HSCs from lineage-committed progenitor HSCs.

Physical form

The product is provided as ascites fluid with 15 mM sodium azide as a preservative.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage freeze in working aliquots. Repeated freezing and thawing, or storage in "frost-free" freezers,is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
