Metanephrine ELISA kits are assays designed to detect metanephrine, a derivative of adrenaline/epinephrine. Also known as metadrenaline, they are metabolic products of catecholamines. Metanephrines can be found in conjugated and unconjugated forms, with the majority in human plasma being conjugated. They are used as biomarkers for rare chromaffin cell tumors such as pheochromocytoma and paraganglioma. Visit the supplier page for more information about detection target, range and reactivity.
