More than twenty years of rodent monoclonal antibody generation by the classical hybridoma technology has yielded a number of promising therapeutic candidates and their humanization compares well to the de novo generation and characterization of human antibodies for accessing clinical applications in the coming years. 

Monoclonal antibodies generated with purified Uri eliminated crossreaction to THP and Iof in urine and plasma, respectively. Antibodies directed at the N-linked glycan allowed measurement of Bik in blood without IqI cross-reactivity. Antibodies directed at the peptide allowed measurement of urinary Bik without THP cross-reactivity. These antibodies do not cross-react with aprotinin. These antibodies allow estimating the Iof family in blood. 

Monoclonal antibodies generated by fusing mouse spleen cells to myeloma cells can be considered as a pure single reagent that is available in unlimited quantity. Drawbacks are high costs, clonal drift and often low affinity.

Fig. 2 Immunoblot analysis of cross-reactivity of monoclonal antibody generated against rat hepatoma thymidylate synthase. T. spiralis muscle larvae crude extract (lane 1 100 pg protein), purified recombinant (lane 2 1 pg protein) or purified muscle larvae endogenous (lane 3 1 pg protein) thymidylate synthase, rat purified regenerating liver endogenous (lane 4 1 pg protein) or rat recombinant (lane 5 1 pg protein) thymidylate synthase and L5178Y crude extract (lane 6 100 pg protein) were separated by SDS polyacrylamide (12%) gel electrophoresis and proteins were transferred into PVDF membrane. Thymidylate synthase was detected by treatment with monoclonal antibody and goat anti-mouse IgG (H + L) - HRP conjugate (BioRad) as a secondary antibody...

The use of the MEl antibody was initially reported by O Hara and colleagues in 1990. " MEl is a monoclonal antibody generated from the mesothelial cell line SPClll and reacted with normal mesothelial cells and malignant epithelial mesotheliomas. Their antibody was only useful on frozen section tissue and showed immunostaining of 40 of 40 (100%) epithelial mesotheliomas. Nineteen well and moderately differentiated primary pulmonary adenocarcinomas failed to stain with the MEl antibody, but one poorly differentiated pulmonary adenocarcinoma showed intense immunostaining. 

Synthetic pvrethroids. Apart from widespread use as household Insecticides, and In treatment of fruit, vegetables, tobacco, and cotton, synthetic pyrethrolds are used for treatment of stock and wool. Some such as (IR)-phenothrln also have public health applications such as treatment of head lice. In different parts of the world, permethrin, bloresmethrln, deltamethrln and natural pyrethrlns are used, and (IR)-phenothrln has been commercially evaluated. Few ELISA assays for pyrethrolds have been developed to date, and those that have, are.for other compounds, such as -bioallethrlnQS), cvpermethrInf 161 and tetramsthrlnf 17 ). We have used monoclonal antibodies generated by collaborators at the University of Callfomia(18) in our initial studies.
