Used in biomedical research to measure levels of brain natriuretic peptide (BNP) in rat models, this ELISA kit helps investigate cardiac function and heart failure. It is widely applied in preclinical studies to assess myocardial stress, monitor disease progression, and evaluate the effectiveness of cardiovascular drugs. Researchers also use it in neuroscience and endocrinology to study the role of BNP in brain-heart interactions, fluid balance, and hormone regulation. The kit enables sensitive and specific detection of BNP in plasma, serum, or tissue samples, supporting accurate quantification for experimental analysis.
