Used in biomedical research to quantify methoxynorepinephrine (MNA) levels in porcine biological samples such as plasma, serum, or tissue extracts. This ELISA kit enables accurate measurement of MNA, a metabolite of norepinephrine, to assess sympathetic nervous system activity in pig models. It is commonly applied in studies related to cardiovascular function, metabolic disorders, and neuroendocrine responses. The assay supports high-throughput analysis with good sensitivity and specificity, making it suitable for preclinical research and veterinary diagnostics. Not intended for human therapeutic or diagnostic use.
