|Other Names||Placenta growth factor, PlGF, PGF, PGFL, PLGF|
|Target/Specificity||Recombinant human PLGF protein|
|Application Note||ELISA : For coating, order Ab without BSA|
Functional Studies : Order Ab without BSA & Azide.
|Format||0.5 ml at 200ug/ml with BSA and azide|
|Storage||Store at 2 to 8°C.Antibody is stable for 24 months.|
|Precautions||PLGF (Placental Growth Factor) Antibody - With BSA and Azide is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Growth factor active in angiogenesis and endothelial cell growth, stimulating their proliferation and migration. It binds to the receptor FLT1/VEGFR-1. Isoform PlGF-2 binds NRP1/neuropilin-1 and NRP2/neuropilin-2 in a heparin-dependent manner. Also promotes cell tumor growth.|
|Cellular Location||Secreted. Note=The three isoforms are secreted but PlGF-2 appears to remain cell attached unless released by heparin|
|Tissue Location||While the three isoforms are present in most placental tissues, PlGF-2 is specific to early (8 week) placenta and only PlGF-1 is found in the colon and mammary carcinomas|

The onset of angiogenesis is believed to be an early event in tumorigenesis and may facilitate tumor progression and metastasis. Several growth factors with angiogenic activity have been described. These include fibroblast growth factor (FGF), platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and placenta growth factor (PlGF). Like VEGF, several PlGF vari- ants have been shown to arise from alternative mRNA splicings. Evidence has suggested VEGF to be an obligatory component in PlGF signaling. While VEGF homodimers and VEGF/PlGF heterodimers function as potent mediators of mitogenic and chemotactic responses in endothelial cells, PlGF homodimers are effectual only at extremely high concentrations. Indeed, many of the physiological effects attributed to VEGF may actually be a result of VEGF/PlGF. VEGF and PlGF share a common receptor, Flt-1, and may also activate Flk-1/KDR.
