Used in biomedical research to quantify potassium urea peptide (KP) levels in human biological samples such as serum, plasma, or urine. The kit enables researchers to study the role of KP in kidney function, electrolyte balance, and metabolic disorders. It is commonly applied in clinical studies investigating hypertension, chronic kidney disease, and disorders related to urea cycle dysfunction. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for both diagnostic research and drug development studies targeting renal and metabolic pathways.
