Used for the quantitative determination of aldosterone levels in rat biological samples such as serum, plasma, or cell culture supernatants. This research kit is specifically designed for use in laboratory studies involving endocrine function, hypertension, and adrenal gland research in rat models. It enables accurate measurement of aldosterone concentration, supporting investigations into electrolyte balance, blood pressure regulation, and responses to stimuli like stress or dietary changes. The assay is widely applied in preclinical studies to evaluate the renin-angiotensin-aldosterone system (RAAS) activity.
