The ratios of hapten and bovine serum albumin (BSA) in an antigen conjugate were determined by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. Hybridomas secreting monoclonal antibodies against 2,4-dichlorophenoxyacetic acid (2,4-D) were produced by fusing 2,4-D-BSA conjugate-immunized splenocytes with a HAT-sensitive mouse myeloma cell line, P3-X63-Ag8-653. A substantial cross-reaction was observed for 2,4-dichlorophenol (2,4-DP) when compared with that observed for 2,4-D. The full measurement range for this assay is 0.2-3 μg ml-1 for 2,4-DP. On the other hand, the range for 2,4-D is between 1 and 20 μg ml -1.
