title: Generation and characterisation of monoclonal antibodies to oleanolic acid.
abstract: Monoclonal antibodies to oleanolic acid, a pentacyclic triterpene, were generated using the hybridoma fusion method described by Kohler and Milstein . Protein conjugates of the target molecule for immunisation were prepared either by directly linking the isoprenoid to different protein carriers via the carboxylic function or after introduction of a succinic spacer between the protein carrier and position 3 of the target molecule. Antibodies of three different cell lines were further analysed by competitive ELISA and were shown to be directed either against both rings A and B or to ring E of the pentacyclic system. Thus these antibodies can be used in the specific detection of oleanolic acid itself or of a broad range of oleanolic acid derivatives sharing a specific structural moiety. Therefore these antibodies may be interesting tools for the screening of putative terpenoid-containing plants.
