Nephrines Plasma Fastrack ELISA [CE]

First, the plasma proteins are removed by precipitation. After this Metanephrine (Metadrenaline) and Normetanephrine Normetadrenaline) are quantitatively acylated. The subsequent competitive ELISA kit uses the microtiter plate format. The antigen is bound to the solid phase of the microtiter plate. The acylated standards, controls and samples and the solid phase bound analytes compete for a fixed number of antiserum binding sites. After the system is in equilibrium, free antigen and free antigen
