Placenta Growth Factor-1 Human Recombinant produced in insect cells is a homodimer, glycosylated polypeptide chain containing 2 x 131 amino acids and having a total molecular mass of approximately 34 kDa. The PLGF-1 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.
PIGF, PGF, PLGF-1, PlGF-2.
Sterile Filtered White lyophilized (freeze-dried) powder.
Lyophilized from a concentrated (1mg/ml) solution containing no additives.
It is recommended to reconstitute the lyophilized Placenta Growth Factor 1 in sterile 0.1M acetic acid or PBS not less than 100
Lyophilized Placenta Growth Factor 1 althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution PLGF1 should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Leu-Pro-Ala-Val.
Greater than 90.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
The ED50 as determined by its ability to bind to immobilized rh-sFlt-1 in a functional ELISA. PlGF-1 human Recombinant can bind to immobilized rh-sFlt-1 (100ng/well) with a linear range at 0.5-10ng/ml, corresponding to a Specific Activity of 1x105-2x106units/mg.
