title: Cloning of a developmentally regulated tegument antigen of Schistosoma mansoni.
abstract: We have cloned a gene encoding a 22.6 kDa antigen from a Schistosoma mansoni cDNA library. Northern blots indicate that transcription of this antigen occurs in adults and sporocysts but not in cercariae, eggs or in newly-transformed schistosomula. Immunoprecipitation and Western blotting with specific antisera indicate that the antigen is not detectable in the newly transformed schistosomulum but appears within 24 h of schistosomulum transformation. Indirect immunofluorescence of adult worms shows this protein to be located in the tegument.
