Used in biomedical research to quantify soluble Liver X Receptor (LXR) levels in human serum, plasma, or cell culture supernatants. This ELISA kit enables researchers to study LXR's role in lipid metabolism, inflammation, and glucose homeostasis. It is particularly valuable in studies related to atherosclerosis, metabolic syndrome, and liver diseases. The assay supports high-throughput screening and therapeutic development targeting nuclear receptors involved in metabolic regulation. Results aid in understanding disease mechanisms and evaluating drug effects on LXR expression in clinical and preclinical settings.
