摘要：
Western immunoblot analyses of whole cell lysates probed with a human specific monoclonal anti-topoisomerase Ilalpha antibody identified a 190 kDa protein over expressed in the arsenite resistant Leishmania donovani strain. The crude nuclear extract of the resistant strain showed higher topoisomerase II-like enzyme activity, suggesting a possible regulatory role of putative topoisomerase II in arsenite resistant Leishmania.
