Used in biomedical research to quantify levels of oxidized phosphatidylcholine in biological samples such as plasma, serum, or tissue homogenates. This assay helps assess oxidative stress-related damage to cell membranes, which is linked to inflammatory diseases, atherosclerosis, neurodegenerative disorders, and metabolic conditions like diabetes. The kit enables high-throughput analysis in studies focused on antioxidant therapies, lipid peroxidation pathways, and disease mechanism exploration. It is not for diagnostic use but serves as a research tool in academic, pharmaceutical, and clinical laboratories.
