Used in neuroscience and cardiovascular research to quantify levels of brain natriuretic peptide (BNP) in mouse brain tissue samples. Helps investigate the role of BNP in central nervous system functions such as regulation of blood pressure, fluid balance, and stress responses. Commonly applied in studies related to heart-brain interactions, neuroendocrine signaling, and pathological conditions like heart failure, stroke, or neurodegenerative diseases. Provides a sensitive and specific method for measuring BNP concentration, enabling researchers to assess changes in peptide expression under experimental treatments or disease models.
