|Cat. No. :
|Product Overview :
||Recombinant Human Placenta Growth Factor-2 produced ininsect cellsis 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.
||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.
|Physical Appearance :
||Sterile Filtered White lyophilized (freeze-dried) powder.
||Greater than 80.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
||Lyophilized from a concentrated (1 mg/ml) solution containing BSA.
||It is recommended to reconstitute the lyophilized Placenta Growth Factor 2 in sterile 20 mM acetic acid not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
|Specific Activity :
||PlGF-2 human Recombinant can bind to immobilized rh-sFlt-1 (100 ng/well) with a linear range at 0.3 – 10 ng/mL.
||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°Cbetween 2-7 days and for future use below -18°C. Please prevent freeze-thaw cycles.
