特徴

• Placenta growth factor (PlGF), a homodimeric glycoprotein that is homologous to vascular endothelial growth factor (VEGF), is mitogenic to endothelial cells and protects trophoblast from apoptosis. Alternative splicing of mature mRNA gives rise to three known isoforms of PlGF. PlGF is expressed by human trophoblast during normal pregnancy, however, it is not known which isoforms are produced.
• Recombinant Human Placenta Growth Factor-1(PIGF/PGF) produced in insect cells is a homodimer, glycosylated polypeptide chain containing 2 x 131 amino acids and having a total molecular mass of 34kD. Recombinant Human PLGF-1 is purified by proprietary chromatographic techniques
• AA Sequence:The sequence of the first five N-terminal amino acids is Met-Leu-Pro-Ala-Val.
• Biological Activity:The ED50 as determined by its ability to bind to immobilized rh-sFlt-1 in a functional ELISA. Recombinant human PlGF-1 can bind to immobilized rh-sFlt-1 (100ng/well) with a linear range at 0.5-10ng/ml.
• Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months after receipt at -20°C. Reconstitute with sterile 0.1M acetic acid. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
