Used in biomedical research to quantify aquaporin-2 protein levels in mouse samples, particularly in studies related to kidney function and water balance regulation. Enables researchers to investigate conditions such as nephrogenic diabetes insipidus, urinary concentration disorders, and the effects of hormones like vasopressin. The kit is commonly applied in preclinical studies using mouse models to assess changes in AQP-2 expression under various physiological or pathological conditions, supporting drug development and mechanistic studies in renal and endocrine research.
