Human Serpin F1, His Tag (SE1-H5221) is expressed from human 293 cells (HEK293). It contains AA Gln 20 - Pro 418 (Accession # NP_002606).
Predicted N-terminus: Gln 20
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 45.2 kDa. The protein migrates as 45-55 kDa under reducing (R) condition (SDS-PAGE).
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl, pH 7.4. Normally trehalose is added as protectant before lyophilization.

erpin F1 (SERPINF1) is also known as Pigment epithelium-derived factor (PEDF), Cell proliferation-inducing gene 35 protein (PIG35). Serpin F1 belongs to the serpin family. Serpin F1 is expressed in quiescent cells. PEDF has a variety of functions including antiangiogenic, antitumorigenic, and neurotrophic properties. Endothelial cell migration is inhibited by SERPINF1/ PEDF. PEDF / SERPINF1 suppresses retinal neovascularization and endothelial cell proliferation. PEDF is also responsible for apoptosis of endothelial cells either through the p38 MAPK pathway or through the FAS/FASL pathway. PEDF also displays neurotrophic functions.
