Assay Principle

The Normetanephrine & Metanephrine ELISA Assay Kit is competitive and uses the microtiter plate format. Metanephrine and normetanephrine, respectively, are bound to the solid phase of the microtiter plate. Acylated nor-/metanephrines from the sample and solid phase bound nor-/metanephrines compete for a fixed number of antiserum binding sites. When the system is in equilibrium, free antigen and free antigen-antiserum complexes are removed by washing. The antibody bound to the solid phase nor-/metanephrine is detected by anti-rabbit IgG / peroxidase. The substrate TMB / peroxidase reaction is monitored at 450 nm. The amount of antibody bound to the solid phase catecholamine is inversely proportional to the catecholamine concentration of the sample.

Additional Information

Assay Background

Normetanephrine and metanephrine are physiologically formed from the catecholamines noradrenaline and adrenaline by the enzyme catechol-O-methyltransferase (COMT). Increased levels of normetanephrine and metanephrine can be found in pheochromocytoma, ganglioneuroma and other neurogenic tumors. The Normetanephrine & Metanephrine (Plasma) ELISA assay kit provides materials for the quantitative measurement of free normetanephrine and metanephrine in EDTA plasma. Normetanephrine and metanephrine are quantitatively acylated to their N-acyl-derivates.
