Storage, Stability and Shipping :The lyophilized protein is stable for at least one year from date of receipt at -70oC. Upon reconstitution, this cytokine can be stored in working aliquots at 2o - 8oC for one month, or at -20oC for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Applications :Cell Assay

Endotoxin Level :<1.0 EU/μg of recombinant protein as determined by the LAL method.

Molecular Weight :45.0 kDa

Gene Aliases :PEDF, SerpinF1, EPC-1, Cell proliferation-inducing gene 35 protein, PIG35, Recombinant Human Pigment Epithelium-Derived Factor (SERPINF1)

Reconstitution Protocol :A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

Scientific Background :Pigment epithelium-derived factor (PEDF), a 50-kDa secreted glycoprotein, is widely expressed throughout the human body, with expression decreasing during human hepatocellular carcinoma and breast cancer progression. PEDF binds to a cell membrane receptor to exhibit multifunctional activity in many cell types but its signaling mechanisms are largely unknown. PEDF exerts anti-angiogenic activity by arresting VEGF- or bFGF-mediated endothelial cell migration, inhibiting capillary morphogenesis, and inducing endothelial cell apoptosis. In human dermal microvascular cells, PEDF induces FasL expression and subsequently activation of caspase 8, which initiates the downstream apoptotic cascade. In human umbilical vein endothelial cells (HUVECs), its induction of apoptosis was shown to depend on p38 MAPK activity and to involve activation of caspases 8 and 9.

Sample Cell Assay Data :The ED(50) was not determined.
