Hydatid cyst fluid has been used as a source of antigen for the serodiagnosis
of Echinococcus granulosus infection. Due to cross-reactions with antigens shared
by other helminthes, the specific antigen from hydatid cyst fluid was purified by
many workers. We used a relatively simple technique for purification of specific
antigen from sheep hydatid cyst fluid. Isopycnic ultracentrifugation with 30%
KEr was used followed by SDS-PAGE to check the purity of the antigen. The
antigen was of 48 kDa and used in ELISA and IRA with high sensitivity and
specificity.
