Data Examples
Immunohistochemistry
VEGF R1/Flt‑1 in Human Breast. VEGF R1/Flt‑1 was detected in immersion fixed paraffin-embedded sections of human breast array using Human VEGF R1/Flt‑1 Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF321) 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). 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.

Background: VEGF R1/Flt-1

VEGF R1 is one of the five receptor tyrosine kinases (RTKs) (Flt-1, KDR/Flk-1, Flt-4, tie-1, and tek/tie-2) whose expression is almost exclusively restricted to the endothelial cells. Tie-1 and tek/tie-2 define a new class of RTKs containing two immunoglobulin-like domains, three EGF homology domains and three fibronectin type III domains in their extracellular regions. Flt-1, KDR/Flk-1 and Flt-4 are members of the class III subfamily of RTKs containing seven immunoglobulin-like repeats in their extracellular domains. All five RTKs are likely to play central roles in vasculogenesis and angiogenesis.

The Flt-1 gene has been localized to chromosome 13q12. Full length Flt-1 mRNA encodes a 1338 amino acid (aa) residue precursor with a 22 aa residue signal peptide. Mature Flt-1 is composed of a 736 aa residue extracellular domain, a 22 aa residue transmembrane domain and a 558 aa residue cytoplasmic domain. As a result of alternative splicing of the mRNA, a cDNA encoding a truncated form of Flt-1, lacking the seventh immunoglobulin-like domain, the transmembrane and intracellular domains, has been cloned.
