| Synonyms | PIGF, PGF, PlGF-2, PLGF-2. |
| Introduction | PLGF is a growth factor active in angiogenesis, and endothelial cell growth, stimulating their proliferation and migration. It binds to receptor vegfr-1/flt1. PLGF-2 binds neuropilin-1 and 2 in a heparin-dependent manner. |
| Description | Placenta Growth Factor-2 Human Recombinant produced in insect cells is a homodimer, glycosylated polypeptide chain containing 2 x 152 amino acids and having a total molecular mass of 44 kDa. The PLGF-2 is purified by proprietary chromatographic techniques. |
| Source | Insect Cells. |
| Physical Appearance | Sterile Filtered White lyophilized （freeze-dried） powder. |
| Formulation | Lyophilized from a concentrated （1mg/ml） solution containing BSA. |
| Solubility | It is recommended to reconstitute the lyophilized Placenta Growth Factor 2 in sterile 20mM acetic acid not less than 100μg/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized Placenta Growth Factor-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution PLGF2 should be stored at 4°C between 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles. |
| Purity | Greater than 80.0% as determined by（a） Analysis by RP-HPLC. （b） Analysis by SDS-PAGE. |
| Biological Activity | PlGF-2 human Recombinant can bind to immobilized rh-sFlt-1 （100ng/well） with a linear range at 0.3 – 10ng/mL. |
| Usage | ProSpec's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
