Schistosoma japonica antigen cDNA clones were identified by lysogenic expression,flat lyiic method and PCR amplification. All 8 positive clones immunologically screened could be expressed in E- coli in the form of fusion proteins with the molecular weight being about 140 to 150 kDa. The positive cDNA genes were digested by restriction endonuclease EcoRI,then the agarose gel electrophoresis revealed the size of them being 700 to 900 bp.
