The low-molecular weight proteins (LMWPs) of Taenia solium metacestode (TsM) constituted pertinent serodiagnostic antigens for cysticercosis. We established a novel single-step purification of the LMWPs from TsM cyst fluid (CF). When the CF was precipitated with trichloroacetic acid/acetone mixture at the final concentrations of 5 and 50%, most LMWPs (ranging 7-38kDa) remained in the supernatant fraction. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblot analyses revealed that the LMWPs consisted mainly with the previously reported subunit proteins of the 120- and 150-kDa antigen complexes. Serum samples from neurocysticercosis (NC) and other helminthic infections, as well as those from healthy controls were tested by both immunoblotting and micro-ELISA. In 135 cases of active stage NC patients, 132 cases (97.7%) showed positive reactions. Serum samples from other helminthic diseases (n=125) and healthy controls (n=100) exhibited no positive reactions except for cystic echinococcosis, of which 12% (3/25 cases) exhibited low levels of cross-reactivity. The LMWPs from different geographical regions (Korea and Mexico) showed diagnostic sensitivity and specificity of 97.7% and 98.7% against active stage NC. Our single-step separation method for the LMWPs provided excellent performance with easy applicability and high reproducibility, which has a great benefit for preparation of potent antigen in endemic areas.
