Chlorothalonil (tetrachloroisophthalonitrile) is a compound which has been widely used as germicide. A competitive enzyme-linked immunosorbent assay (ELISA) was developed for the detection of residual chlorothalonil in crops. Three monoclonal antibodies, mAbs 12E, 9A, and 11D were generated against bovine serum albumin-comjugated pentachlorophenol as a homologue of chlorothalonil. By using these mAbs, a direct competitive ELISA has been done. Detectable range of chlorothalonil in the ELISA was 1-3ng/ml for mAb 12E and 0.3-3ng/ml for both mAbs 11D and 9A. MAb 9A reacted with chlorothalonil 3 times stronger than another structurally related germicide fthalide, while mAb 11D reacted with fthalide 5 times stronger than chlorothalonil. The proposed ELISA with mAb 9A would be useful for convenient monitoring of residual chlorothalonil in crops.
