Used in biomedical research to quantify levels of the nuclear receptor NR4A1 (also known as NUR77) in mouse samples. This ELISA kit enables researchers to measure protein expression in cell lysates, tissue homogenates, and biological fluids, supporting studies in inflammation, apoptosis, metabolic regulation, and cancer. It is particularly valuable in immunology and neuroscience research where NR4A1 plays a regulatory role in immune cell function and neuronal survival. The assay provides a sensitive and specific method for high-throughput analysis in preclinical studies.
