MEG-encoded proteins are secreted by migrating schistosomula and mature eggs. (A) 2D electrophoretic separation of secretions released from skin-stage schistosomula between 3 h and 3 d of in vitro culture. (B) 2D electrophoretic separation of the less abundant egg-secreted proteins (ESPs) after lectin depletion of the major ESP1-6 proteins. Spot numbers inside the block arrows (A) or circles (B) correspond to the MS data in Supplemental Table 6. The MEG family number is adjacent to each spot or spot group.
