Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human ANGPTL3 protein.
Background
Angiopoietin-like 3 (ANGPTL3) is a secreted protein primarily expressed in liver and a regulator of fatty acid homeostasis (1). The angiopoietin-like family contains a signal peptide, an N-terminal coiled-coil domain (CCD), a linker peptide, and a C-terminal fibrinogen-like domain (FLD). Cleavage of the CCD and FLD occurs within the linker peptide, and is required for the activity of both domains (2). ANGPTL3-CCD, in concert with ANGPTL4/ANGPTL8, increases circulating triglyceride levels by inhibiting lipoprotein lipase, a hydrolase of LDL cholesterol (2,3). ANGPTL3-CCD also directly inhibits endothelial lipase, the enzyme responsible for HDL cholesterol hydrolysis (8,9). Thus, ANGPTL3-deficient mice have low levels of plasma HDL cholesterol, a risk factor for atherosclerosis (8,9). Unlike traditional angiopoietins, ANGPTL3-FLD does not bind the Tie2 receptor (4). ANGPTL3-FLD has been demonstrated to stimulate angiogenesis in endothelial cells via binding to integrin αVβ3, and to facilitate lipolysis in adipocytes via stimulation of the PDGFRβ-BRAF-ERK pathway (4,5). ANGPTL3 is currently a therapeutic target in patients with high-LDL dyslipidaemia, and can be inhibited with the use of monoclonal antibodies or antisense nucleotides (6,7).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
