Unusual protein pattern of Opisthorchis viverrini

The proteins of homogenized adult Opisthorchis viverrini were separated by polyacrylamide gel electrophoresis and isoelectric focusing in the presence of detergents. By far the most abundant component(s) had a Mr of 18,000 to 19,000, represented about 47% of the total parasite protein, and did not separate in isotypes.
