蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 27.9 kDa. The protein migrates as 31-35 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）
>95% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in 50 mM MOPS, 100 mM NaCl, pH7.2. Normally trehalose is added as protectant before lyophilization.

背景（Background）
Angiopoietin-related protein 4 (ANGPTL4) is also known as Hepatic fibrinogen / angiopoietin - related protein (HFARP), ARP4, PGAR. ANGPTL4 contains one fibrinogen C-terminal domain. ANGPTL4 is a homooligomer , and the homooligomer undergoes proteolytic processing to release its carboxyl fibrinogen-like domain, which circulates as a monomer. The homooligomer unprocessed form is able to interact with the extracellular matrix. ANGPTL4 may act as a regulator of angiogenesis and modulate tumorigenesis. ANGPTL4 inhibits proliferation, migration, and tubule formation of endothelial cells and reduces vascular leakage. ANGPTL4 may exert a protective function on endothelial cells through an endocrine action.
