The authors characterized the proteins of the crude antigen obtained from Clonorchis sinensis worm and excretory-secretory and billis from rabbits, experimentally infected for 3 months. Protein composition was observed after adding a cysteine proteinase inhibitor E-64 and a serine proteinase inhibitor PMSF, respectively. SDS-PAGE of the crude antigen from C. sinensis recovered from the infected rabbits, the crude antigen from the adult worm excretory-secretory, and the crude antigen from billis of the rabbits resolved 26, 27 and 19 profiles between 200-9 kDa, respectively. When E-64 supplemented 29, and 22 bands, respectively. More study should be carried out in the future on the immunological characteristics and the monoclonal antibody of the each antigen.
