Abstract

CBA and BALB/c mice produced polyspecific and monospecific polyclonal antibody responses, respectively, following immunization with Wuchereria bancrofti stage-3 larvae. Two monoclonal antibodies (MAbs) were produced from the immunized BALB/c mouse. These MAbs (both isotype M) recognized a previously undescribed highly expressed W. bancrofti antigen present in stage-3 larvae. The epitopes bound by the MAbs appear to be species specific for W. bancrofti since the MAbs did not bind to antigens of either nine other nematode species or two vector species in Western blots (immunoblots). Phosphorylcholine epitopes, responsible for immunological cross-reactivity among nematodes, were identified only on a 200-kDa antigen and not on the 95-kDa molecule. The targets of these immunoglobulin M MAbs are not carbohydrate epitopes.
