VEGF Receptor 2 in Human Placenta.
Vascular Endothelial Cell Growth Factor Receptor 2 (VEGF R2)/KDR/Flk-1 was detected in immersion fixed paraffin-embedded sections of human placenta using Human VEGF R2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF357) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-AEC Cell & Tissue Staining Kit (red; Catalog # CTS009) and counterstained with hematoxylin (blue).

This antibody specifically recognizes human VEGF R2. Reactivity with VEGF R2 from other species has not been determined.

VEGF Receptor 2 in Mouse Embryo.
Vascular endothelial growth factor receptor 2 (VEGF R2)/KDR/Flk-1 was detected in immersion fixed frozen sections of mouse embryo (14 d.p.c.) using Mouse VEGF R2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF644) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to mesenchymal cells.
VEGF Receptor 2 in Human Placenta.
Vascular endothelial cell growth factor receptor 2 (VEGF R2)/KDR/Flk-1 was detected in immersion fixed paraffin-embedded sections of human placenta using Human VEGF R2 Monoclonal Antibody (Catalog # MAB3571) at 25 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue).

VEGF R2/KDR/Flk-1 in Human Kidney.
Vascular Endothelial Growth Factor Receptor 2 (VEGF R2/KDR/Flk-1) was detected in immersion fixed paraffin-embedded sections of human kidney using Human VEGF R2/KDR/Flk-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF357) at 10 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.
