Used in biomedical research to measure levels of N-terminal prohormone of brain natriuretic peptide (NT-proBNP) in rat samples. This kit helps assess cardiac function and heart stress in preclinical studies. It is commonly applied in research on heart failure, myocardial injury, and cardiovascular diseases in rat models. The assay enables sensitive and specific quantification of NT-proBNP, allowing researchers to monitor disease progression or response to treatment. Widely used in pharmacology, toxicology, and experimental cardiology for reliable biomarker detection.
