PlGF in Human Placenta. PlGF was detected in formalin fixed paraffin-embedded sections of human placenta using Sheep Anti-Human PlGF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6837) at 10 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to syncytiotrophoblasts. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: PlGF

Placenta Growth Factor (PlGF) is a member of the Vascular Endothelial Growth Factor (VEGF) family of growth factors. PlGF and VEGF share primary structural as well as limited amino acid sequence homology with the A and B chains of PDGF. All eight cysteine residues involved in intra- and inter-chain disulfides are conserved among these growth factors. In their PDGF-like regions, VEGF and PlGF also share approximately 53% amino acid sequence similarity. The gene for PlGF has been mapped to chromosome 14. As a result of alternative splicing, at least two PlGF mRNAs encoding monomeric PlGF precursors containing 149 and 170 amino acid residues have been described. The expression of PlGF is not widespread, but has been detected in human umbilical vein endothelial cells, placenta, choriocarcinoma cell lines, and in renal cell carcinoma associated with angiogenesis. The PlGF proteins bind with high-affinity to Flt-1, but not to Flk-1/KDR.
