Enzyme immunoassay (ELISA) for the determination of free Metanephrine and free Normetanephrine in plasma.<br><br>
Metanephrine (Metadrenaline) and Normetanephrine (Normetadenaline) are first extracted using an ion exchange matrix followed by an acylation process.<br><br>
The subsequent competitive ELISA uses the microtiter plate format. The antigen is bound to the solid phase of the microtiter plate. The acylated standards, controls and samples compete with the solid phase bound analytes for a fixed number of antibody binding sites. After the system is in equilibrium, free antigen and free antigen-antibody complexes are removed by washing. The antibody bound to the solid phase is detected by an anti-rabbit IgG-peroxidase conjugate using TMB as a substrate. The reaction is monitored at 450nm.<br><br>
Determination of unknown samples is achieved by comparing their absorbance with a reference curve prepared with known standards. For research use only, not for use in diagnostic procedures.
