Two enzyme-linked immunosorbent assays (ELISA) with chemiluminescent (CL) detection for the insecticide DDT and the group of DDT-related compounds have been optimized and characterized. Both conjugate-coated ELISAs are based on monoclonal antibodies (MAbs) of different specificity and homologous protein conjugates. Effects of several physicochemical factors (ionic strength, pH, Tween-20 and Bovine serum albumin (BSA) concentrations) and solvents (methanol, ethanol, acetone and N,N'-dimethylformamide) on the performance of the assays were studied and optimized. For the DDT-selective assay, the sensitivity, estimated as the I(50) value, was 0.6 microg/l, with a linear working range between 0.1 and 2 microg/l and a limit of detection of 0.06 microg/l. For the DDT group-selective assay, the sensitivity was 0.2 microg/l, with a linear working range between 0.07 and 1 microg/l and a limit of detection of 0.04 microg/l. CL-ELISAs were four times more sensitive compared to colorimetric ELISAs. Finally, both immunoassays were applied to the detection of DDT and group of DDT-related compounds in spiked real water, soil and food samples.
