Used in research settings to quantify mid-regional pro-atrial natriuretic peptide (MR-proANP) levels in human plasma or serum. This immunoassay kit helps assess cardiac function and is commonly applied in studies related to heart failure, cardiovascular diseases, and renal function. Due to its stability and strong correlation with atrial natriuretic peptide release, MR-proANP serves as a reliable biomarker for early detection and prognosis of acute and chronic heart conditions. The kit supports quantitative measurement with high sensitivity and specificity, making it suitable for clinical research, drug development, and epidemiological studies focused on cardiovascular health.
