В работе использованы гибридомы, продуцирующие моноклональные антитела к шигаподобным токсинам I и II типов, полученные в филиале ФГБУ «48 ЦНИИ» Минобороны России (г. Киров); мыши линии BALB/c; шигаподобные токсины I и II типов. Клетки гибридом культивировали в культуральных флаконах и в перитонеальной полости мышей линии BALB/с. Моноклональные антитела выделяли из асцитических жидкостей путем осаждения насыщенным раствором сульфата аммония с последующей очисткой ионообменной хроматографией. Полученные препараты моноклональных антител использовали для конструирования иммуноферментных тест-систем для выявления шигаподобных токсинов I и II типов. Специфические компоненты иммуноферментных тест-систем подвергали сублимационному высушиванию в защитной среде. </p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. В результате проведённых исследований осуществлена наработка и очистка препаративных количеств моноклональных антител к шигаподобным токсинам I и II типов; проведен выбор моноклональных антител для сорбции на твёрдой фазе и для синтеза иммунопероксидазных конъюгатов. </p></sec><sec><title>Заключение</title><p>Заключение. сконструирована экспериментальная иммуноферментная тест-система, позволяющая в сэндвич-варианте иммуноферментного анализа выявлять шигаподобные токсины I и II типов в концентрации 1 нг/мл и более.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The aim of the work was development of enzyme immunoassay for detecting I and II types of shiga-like toxins and assessment of it diagnostic properties. </p></sec><sec><title>Materials and methods</title><p>Materials and methods. For the research, we used hybridomas producing monoclonal antibodies to shiga-like toxins of types I and II, obtained at the branch of the Federal State Budgetary Institution “48 Central Research Institute” of the Ministry of Defense of Russian Federation (Kirov); BALB/c mice; shiga-like toxins of types I and II. Hybridoma cells were cultured in culture flasks and in the peritoneal cavity of BALB/c mice. Monoclonal antibodies were isolated from ascitic fluids by precipitation with a saturated solution of ammonium sulfate, followed by purification by ion exchange chromatography. The obtained preparations of monoclonal antibodies were used to develop enzyme immunoassay for the detection of shiga-like toxins of types I and II. Specific components of enzyme immunoassay were freeze-dried in a protective environment.</p></sec><sec><title>Results</title><p>Results. As a result of research, preparative quantities of monoclonal antibodies against I and II types of shiga-like toxins were obtained and purified; selection of monoclonal antibodies for sorption on the solid phase and for the synthesis of immunoperoxidase conjugates was carried out. </p></sec><sec><title>Conclusion</title><p>Conclusion. Experimental enzyme immunoassay allowing to identify 1 ng/ml I and II types of shiga-like toxins in «sandwich»-ELISA was developed.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>шигаподобные токсины</kwd><kwd>моноклональные антитела</kwd><kwd>тест-система</kwd><kwd>иммуноферментный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>shiga-like toxins</kwd><kwd>monoclonal antibodies</kwd><kwd>enzyme immunoassay</kwd><kwd>ELISA</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">Мelton-Celsa A.R.
