Product Overview
This rabbit polyclonal antibody detects angiopoietin-related protein 4 (gene ANGPTL4) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 45.2 kDa, and the supplier reports an observed band at about 40–50 kDa.
ANGPTL4 is a secreted protein that inhibits lipoprotein lipase, reducing triglyceride uptake in tissues such as adipose tissue during fasting. Its expression is induced by fasting and PPAR signaling, and it is studied in lipid metabolism, vascular permeability and cancer.

Recombinant human ANGPTL4 fragment (Asp39–Ser406), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 75.6% and 76.6%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt describes angiopoietin-related protein 4 as a secreted protein. Tissue expression noted by UniProt (human): Detected in blood plasma (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
