A two-site time-resolved fluoroimmunoassay (TRFIA) of CA 125 based on the direct sandwich technique has been developed
with the equilibrium method. The monoclonal antibody (MoAb) against CA 125 was labelled with europium by the help of europium-chelate of diethylenetriaminepentaacetic acid (DTPA). The luminescent enhancement system was an enhancement solution that contained mainly of 2-naphthoyltrifluoroacetone. The intra- and inter- assay CV of the TRFIA were 4.5% and 4.0%
respectively
and the recovery rate was 96.7%
the sensitivity was 3.3μg/mL. The cross-reacting rate with CEA was negligible
