Это достигается использованием рекомбинантного штамма холерного вибриона, продуцирующего вместо холерного токсина только его В-субъединицу, благодаря чему выделяемый препарат не обладает остаточной токсичностью. В данной работе мы использовали метод колоночной гельпроникающей хроматографии, который обеспечивает сохранение стабильного нативного состояния и максимальный выход антигена. Предлагаемый способ был отработан опытным путем, в процессе которого после каждого этапа колоночной гель-хроматографии на TSK-геле HW-60 чистоту образца анализировали с помощью диск-электрофореза, в результате чего выяснили, что трех ступеней очистки достаточно для получения лишенного примесей препарата В-субъединицы холерного токсина. Иммунологическая активность очищенной В-субъединицы подтверждена получением моноклональных антител. Полученный препарат В-субъединицы холерного токсина и моноклональные антитела к ней могут служить основой конструирования различных вариантов иммунодиагностических тест-систем.</p></abstract><trans-abstract xml:lang="en"><p>Put forward is an efficient method for manufacturing cholera toxin B-subunit. Its advantages are relative simplicity and economy feasibility, as well as maximum output of the purified B-subunit, absolutely free from toxic A-subunit contaminant. All this is due to the deployment of cholera vibrio recombinant strain producing only cholera toxin B-subunit instead of cholera toxin as it is, which results in lack of residual preparation toxicity. Applied has been gel-penetration column chromatography, providing for stable native state and maximum antigen output. The method under discussion is verified experimentally. Sample purity has been analyzed after each phase of chromatographic investigation on TSK gel HW-60, using disc electrophoresis. It is established that three steps of purification are ample for the obtainment of cholera toxin B-subunit preparation free from admixtures. Immunological activity of the purified B-subunit is validated by monoclonal antibody obtainment. Designed preparation of cholera toxin B-subunit and monoclonal antibodies to it can serve as a basis for the development of various immune-diagnostic test-systems alternatives.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>В-субъединица холерного токсина</kwd><kwd>гель-хроматография</kwd><kwd>Vibrio cholerae</kwd><kwd>cholera toxin B-subunit</kwd><kwd>gel-penetration column chromatography</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Захарова Т.Л., Киреев М.Н., Ливанова Л.Ф., Заднова С.П., Смирнова Н.И.
