Rabbit Anti-PLGF/FITC Conjugated antibody
background:
The placental-derived growth factor (PIGF) is a dimeric glycoprotein showing a high degree of sequence similarity to the vascular endothelial growth factor. Alternative splicing of the PIGF primary transcript gives rise to two forms, named PIGF-1 and PIGF-2, which differ only in the insertion of a highly basic 21-amino acid stretch at the carboxyl end. The presence of the PIGF mRNA in thyroid, placenta, lung, and goiter has indicated the tissues where this factor functions. However, the role of PIGF in vascular development has not yet been clearly established.
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.
Subunit:
Antiparallel homodimer; disulfide-linked. Also found as heterodimer with VEGFA/VEGF (By similarity).
Subcellular Location:
Secreted. The three isoforms are secreted but PlGF-2 appears to remain cell attached unless released by heparin.
Tissue Specificity:
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.
Similarity:
Belongs to the PDGF/VEGF growth factor family.

PLGF胎盘生长因子是血管生长因子家族成员之一，是动脉粥样硬化斑块不稳定的主要炎性激活物，因此它可作为ACS患者风险预测的生物学标志物.尿胎盘生长因子水平可预测先兆子痫危险.研究人员发现，在疾病发作前的6到8周，先兆子痫患者尿液中的胎盘生长因子水平急剧下降,这种新的尿检方法使提前1到2个月预测先兆子痫成为可能。亦有研究人员正在从事胎盘生长因子与肺气肿，胃癌，肠癌等方面的研究。
