Product details:
Human ANGPTL3 ELISA Kit (ab254510) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of ANGPTL3 protein in cell culture media, edta plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human ANGPTL3 with 103.25 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
ANGPTL3 (Angiopoietin-like 3) is a glycoprotein made in the liver and involved in lipid metabolism. ANGPTL3 can inhibit endothelial lipase and ANGPTL3 levels correlate with plasma HDL cholesterol, implicating it in modulation of HDL levels. ANGPTL3 expression is also associated with triglyceride levels, as loss of function mutations in ANGPTL3 is often found in individuals with low plasma triglyceride levels. Additionally, interference of ANGPTL3 interactions with LPL (the enzyme that hydrolyzes circulating triglycerides) in mice resulted in a reduction of serum triglyceride levels.

ANGPTL3 also known as angiopoietin-like protein 3 or betatrophin is a protein that functions mechanistically in lipid metabolism. It consists of approximately 70 kDa mass and is expressed mainly in the liver. ANGPTL3 is synthesized and secreted as a glycoprotein and it undergoes post-translational modifications important for its function. The protein exists predominantly in a monomeric form in circulation.
Biological function summary
ANGPTL3 inhibits lipoprotein lipase (LPL) activity to regulate plasma lipid levels. It independently interacts with lipids and facilitates the storage of triglycerides making it an important modulator of lipid metabolism. ANGPTL3 does not form a stable complex with other proteins but modulates the presence and stability of LPL on the endothelial surface reducing lipid clearance. ANGPT1 ELISA can measure ANGPTL3 levels as part of routine assays including ANGPTL3 ELISA and beta-trophin ELISA.
Pathways
ANGPTL3 plays a central role in the lipid metabolism and energy homeostasis pathways. In the lipid metabolism pathway ANGPTL3's ability to inhibit LPL links it to other proteins involved in lipid transport and storage such as LDL and HDL particles. Another related protein ANGPTL4 shares similar functions with ANGPTL3 indicating a level of redundancy and regulation within these pathways. ANGPTL3 like ANGPTL4 is a significant player in balancing lipid processing and storage.
ANGPTL3 strongly associates with hyperlipidemia and atherosclerosis. Abnormalities in ANGPTL3 levels can lead to altered lipid profiles raising the risk for cardiovascular diseases. Familial combined hypolipidemia involves mutations in the ANGPTL3 gene leading to drastically lower lipid levels. Disorders such as hypercholesterolemia also demonstrate connections with ANGPTL3 highlighting its role in lipid imbalance. These associations make the anti-ANGPTL3 antibodies important for the study and treatment of such lipid disorders.
