title: [Obtaining and construction of a novel gene from Schistosoma japonicum by expressed sequence tags].
abstract: OBJECTIVE
  To look for new candidate vaccine molecule and characterize new genes from Schistosoma japonicum.
  
  
  METHODS
  New genes of S. japonicum were obtained through expressed sequence tags and analyzed on line. One interest cDNA was cloned into anti-sense eukaryotic expression vector.
  
  
  RESULTS
  An interest cDNA JAYL0230 was obtained. Analysis showed that homology existed between its deduced amino acid sequence and defender against apoptotic death 1 of human and pig, etc. Its anti-sense cDNA was cloned into eukaryotic expression vector pEGFP-N3.
  
  
  CONCLUSIONS
  The combination of expressed sequence tags and bioinformatics is an effective way to find novel genes of creature. Construction of anti-sense eukaryotic vector is helpful in studying gene's function.
