蛋白结构(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 42.8 kDa. The protein migrates as 48-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
纯度(Purity)
>90% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in 20 mM Sodium Acetate, 100 mM NaCl, pH6.5. Normally trehalose is added as protectant before lyophilization.

背景(Background)
SERPINE2 is also known as Glia-derived nexin (GDN), Peptidase inhibitor 7 (PI7), Protease nexin 1(PN1). SERPINE2 is a secreted glycoprotein which belongs to the serpin family. SerpinE1 is the primary physiological inhibitor of the two plasminogen activators urokinase (uPA) and tissue plasminogen activator (tPA). PAI-1 / GDN is also implicated in adipose tissue development. It suggests that PAI-1 inhibitors serve in the control of atherothrombosis. Defects in Serpin E1 / PN1 are the cause of plasminogen activator inhibitor-1 deficiency (PAI-1 deficiency) which is characterized by abnormal bleeding due to SerpinE1 defect in the plasma.
