In silico Analysis of Immunologic Regions of Surface Antigens (Sags) of Toxoplasma gondii
<h2>Background: Surface antigens (SAGs) of Toxoplasma gondii are known candidates for diagnostic tests and vaccines. The present study argues about the main necessary properties for determination and prediction of T-cell agretopes and B-cell epitopes of surface antigens of Toxoplasma gondii.&l...

description | <h2>Background: Surface antigens (SAGs) of Toxoplasma gondii are known candidates for diagnostic tests and vaccines. The present study argues about the main necessary properties for determination and prediction of T-cell agretopes and B-cell epitopes of surface antigens of Toxoplasma gondii.</h2><p><strong>M</strong><strong>aterials and Methods: </strong>Primary, secondary and tertiary structures of the proteins were analyzed by different methods.
