Identification of IgE and IgG1 specific antigens in Echinococcus granulosus cyst fluid

Cystic echinococcosis (CE) is an anthropozoonotic disease with worldwide distribution and is caused by the cestode Echinococcus granulosus. Anaphylactic shock induced by CE rupture is a serious complication especially in patients with hydatid infections, as the resulting leakage of fluid contains highly toxic endogenous antigen. We aimed to isolate and identify the antigens of specific IgE and IgG1 (sIgE and sIgG1) in E. granulosus cyst fluid (EgCF). Crude antigen for EgCF was prepared from E. granulosus-infected sheep liver. Antigens were separated and identified by one-dimensional sodium dod...
