| purification of larval taenia solium antigens by isoelectric focusing. | by preparative isoelectric focusing in a rotating ampholine column, crude cystic membrane (m) or fluid (f) antigens of larval taenia solium were each separated into 20 fractions. m fractions were less specific and sensitive than f fractions in detecting cysticercosis antibodies in pig serum. among the f fractions, f15 showed the best potential to serve as a screening antigen. it contained 18 polypeptides, with pi 5.3-8.2 and a specific epitope of 25 kda which was detected by immunoblotting. alth ... | 1998 | 9561707 |
