Used in biomedical research to quantify apelin-12 levels in mouse samples, particularly in studies related to cardiovascular function, metabolic regulation, and fluid homeostasis. The kit enables accurate measurement of apelin-12 peptide concentrations in plasma, serum, or tissue homogenates, supporting research on heart failure, hypertension, diabetes, and obesity. Its high sensitivity and specificity make it suitable for investigating the role of the apelinergic system in physiological and pathological conditions. Widely used in preclinical studies and drug development targeting G-protein coupled receptors.
