Adrenaline/Noradrenaline ELISA 试剂盒

Adrenaline (epinephrine) and noradrenaline (norepinephrine) are extracted by using a cisdiolspecific affinity gel, acylated and then derivatized enzymatically. The competitive ELISA kit uses the microtiter plate format. The antigen is bound to the solid phase of the microtiter plate. The derivatized 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 antigenand free antigenantiserum complexes are removed by washing. The antibody bound to the solid phase is detected by an antirabbit IgGperoxidase conjugate using TMB as a substrate. The reaction is monitored at 450 nm. Determination of unknown samples is achieved by comparing their absorbance with a reference curve prepared with known standard concentrations.
