Placental growth factor (PGF) 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.

Recombinant Human PlGF Protein (rhPGF) Leu 19 - Arg 170 (Accession # NP_002623.2) was produced in human 293 cells (HEK293).

Molecular Characterization
rhPGF, fused with 6×His tag at the C-terminus, has a calculated MW of 20.2 kDa. The predicted N-terminus is Leu 19. DTT-reduced Protein migrates as 28-33 kDa due to glycosylation.

Less than 1.0 EU per μg of the rhPGF by the LAL method.

>95% as determined by SDS-PAGE.

Lyophilized from 0.22 μm filtered solution in 100 mM acetic acid, pH2-3. Normally Mannitol or Trehalose are added as protectants before lyophilization.

See Certificate of Analysis for details of reconstitution instruction and specific concentration.

Avoid repeated freeze-thaw cycles.
No activity loss was observed after storage at:
In lyophilized state for 1 year (4°C-8°C); After reconstitution under sterile conditions for 1 month (4°C-8°C) or 3 months (-20°C to -70°C).
