Description
Placental Growth Factor-2 Human Recombinant produced in E.Coli is a non-glycosylated, disulfide-linked homodimer consisting of 2x152 amino acid polypeptide chains, having a total molecular mass of approximately 34.6kDa. PLGF2 is purified by proprietary chromatographic techniques.
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 dependent way.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4 and 0.02 % Tween-20.
Stability
Lyophilized PLGF2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Placental Growth Factor-2 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 97.0% as determined by: (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
Biological Activity
Determined by its ability to chemoattract human monocytes using a concentration range of 5.0-50 ng/ml.
