Placenta growth factor (PlGF) is a member of the vascular endothelial growth factor (VEGF) family of growth factors. 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 VEGF R1/Flt-1 but not to VEGF R2/Flk-1.

Detection of Human PLGF by Block/Neutralize
Anti-PlGF neutralising antibody blocks DMOG-induced inhibition of ECFC tube formation. ECFCs were stained with calcein (Invitrogen) and grown on Matrigel®. Cells were treated with conditioned medium harvested from ECFCs treated with a DMSO (vehicle) plus isotype control IgG, b DMOG plus isotype control IgG, c DMSO plus anti-PlGF neutralising antibody or d DMOG plus anti-PlGF neutralising antibody. e At 48 h, total tube area (μm2) was quantified using NIS Elements software (Nikon). Data plotted as mean ± SD and are representative of three independent experiments. **p < 0.01; ***p < 0.001. Scale bars: 200 μm (n = 3).

Human PlGF ELISA Standard Curve
Recombinant Human PlGF (Catalog # 264-PGB) was serially diluted and captured by Mouse Anti-Human PlGF Monoclonal Antibody (Catalog # MAB264) coated on a Clear Polystyrene Microplate (Catalog # DY990). Goat Anti-Human PlGF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-264-PB) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998)Applications for Human PlGF Antibody (37203)
