- SynonymPGF,PLGF,PlGF,PGFL,SHGC-10760
- SourceHuman PLGF (19-149), His Tag (PGF-H52H5) is expressed from human 293 cells (HEK293). It contains AA Leu 19 - Arg 149 (Accession # P49763-2).Predicted N-terminus: Leu 19Request for sequence
- Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 16.6 kDa. As a result of glycosylation, the protein migrates as 20-30 kDa under reducing (R) condition, and 45-55 kDa under non-reducing (NR) condition (SDS-PAGE).
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>90% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

- BackgroundPlacental growth factor (PGF) is also known as vascular endothelial growth factor-related protein, PLGF and PlGF2, is a member of the VEGF (vascular endothelial growth factor) sub-family - a key molecule in angiogenesis and vasculogenesis, in particular during embryogenesis. The main source of PGF during pregnancy is the placental trophoblast. PGF is also expressed in many other tissues, including the villous trophoblast. PGF is actived in angiogenesis and endothelial cell growth, stimulating their proliferation and migration. PlGF2 binds NRP1/neuropilin-1 and NRP2/neuropilin-2 in a heparin-dependent manner. Also promotes cell tumor growth.
