Detection of VEGF R2/KDR/Flk‑1 in bEnd.3 Mouse Cell Line by Flow Cytometry.
bEnd.3 mouse endothelioma cell line was stained with Rat Anti-Mouse VEGF R2/KDR/Flk‑1 Monoclonal Antibody (Catalog # MAB4432, filled histogram) or isotype control antibody (Catalog # MAB005, open histogram), followed by Allophycocyanin-conjugated Anti-Rat IgG F(ab')2 Secondary Antibody (Catalog # F0113).
VEGF R2/KDR/Flk‑1 in bEnd.3 Mouse Cell Line.
VEGF R2/KDR/Flk‑1 was detected in immersion fixed bEnd.3 mouse endothelioma cell line using 10 µg/mL Rat Anti‑Mouse VEGF R2/KDR/Flk‑1 Monoclonal Antibody (Catalog # MAB4432) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counterstained with DAPI (blue).

Background: VEGF R2/KDR/Flk-1
VEGF R2 (KDR/Flk-1), VEGF R1 (Flt-1) and VEGF R3 (Flt-4) belong to the class III subfamily of receptor tyrosine kinases (RTKs). All three receptors contain seven immunoglobulin-like repeats in their extracellular domains and kinase insert domains in their intracellular regions. The expression of VEGF R1, 2, and 3 is almost exclusively restricted to endothelial cells. These receptors are likely to play essential roles in vasculogenesis and angiogenesis. Mature mouse VEGF R2 is composed of a 743 amino acid (aa) extracellular domain, a 22 aa transmembrane domain, and a 583 aa cytoplasmic domain. In contrast to VEGF R1 which binds both PlGF and VEGF with high affinity, VEGF R2 binds VEGF but not PlGF with high affinity.
