Used in research to study atherosclerosis and cardiovascular diseases by detecting oxidized low-density lipoprotein (oxLDL) immune responses. The Fc tag enables easy detection and purification, making it valuable in immunoassays and binding studies. Commonly used in ELISA, flow cytometry, and protein-protein interaction experiments to investigate the role of oxLDL in inflammation and plaque formation. Also supports development of therapeutic antibodies and diagnostic tools targeting cardiovascular conditions.
