Proteins were extracted from F. hepatica collected on cattle and sheep. The extract was purified in the column with sephadex G-25. The proteins were separated using the Davis method in electrophoretic systems constructed by the authors, in the columns and in blocks in polyacrylamid gel. The electrophoregrams served for making densometric diagrams and for calculating electrophoretic mobility coefficient (Rf) of the identified protein bands. Both in the blocks and in the columns 26 protein bands have been identified in F. hepatica from both cattle and sheep. Statistical analysis with t Student test showed significant differences in their Rf values. A high reproducibility of the results has been obtained both in the columns and in the blocks of polyacrilamid gel.
