Unusual protein pattern ofOpisthorchis viverrini

Abstract
The proteins of homogenized adultOpisthorchis viverriniwere separated by polyacrylamide gel electro-Phoresis 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.
