Одним из важных этапов получения данной категории препаратов является процесс адсорбции и удаления перекрестнореагирующих антител для повышения специфичности препарата. С этой целью используются инактивированные клетки штаммов Yersinia pseudotuberculosis.</p><p>Цель работы – оценка возможности применения иммунохимических методов для анализа адсорбционных свойств бактериальных клеток, с последующим анализом влияния условий культивирования, способа культивирования, варианта используемого штамма на адсорбционные свойства бактериальных клеток.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Культивирование проводили на плотной и жидкой питательных средах, инактивацию клеток проводили путем температурного и химического воздействия. Оценку адсорбционной активности осуществляли методами иммуноблоттинга и ингибирующего иммуноферментного анализа.

Показана применимость методов иммуноблоттинга и ингибирующего ИФА для качественной и количественной оценки адсорбционных свойств бактериальных клеток. Установлено, что на адсорбционные свойства бактериальных клеток влияет способ инактивации и внесение субстратной подкормки, способ культивирования не оказывает воздействия на адсорбционные свойства клеток.</p></sec></abstract><trans-abstract xml:lang="en"><p>Currently, the Russian Anti-Plague Institute “Microbe” produces diagnostic immunoglobulins used in laboratory diagnostics of plague pathogen. One of the important stages in obtaining this category of drugs is the process of adsorption and removal of cross-reacting antibodies to increase the specificity of the drug. For this purpose, inactivated cells of Yersinia pseudotuberculosis strains are used.</p><p>The aim of the work was to assess the possibility of using immunochemical methods to analyze the adsorption properties of bacterial cells, followed by an assessment of the impact of cultivation method and conditions, and the variant of the strain used on the adsorption properties of bacterial cells.</p><sec><title>Materials and methods</title><p>Materials and methods. Cultivation was carried out on solid and liquid nutrient media; cells were inactivated by temperature and chemical exposure. Adsorption activity was assessed using immunoblotting and inhibitory enzyme-linked immunosorbent assay. Statistical processing of the results was performed using two-factor analysis of variance.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The suitability of immunoblotting and inhibitory ELISA methods for qualitative and quantitative assessment of the adsorption properties of bacterial cells has been demonstrated. It has been established that the adsorption properties of bacterial cells are influenced by the method of inactivation and the application of substrate feeding; the method of cultivation does not affect the adsorption properties of cells.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>иммуноглобулины диагностические чумные</kwd><kwd>Yersinia pseudotuberculosis</kwd><kwd>адсорбция перекрестнореагирующих антител</kwd><kwd>ингибирующий иммуноферментный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diagnostic plague immunoglobulins</kwd><kwd>Yersinia pseudotuberculosis</kwd><kwd>adsorption of cross-reacting antibodies</kwd><kwd>inhibitory enzyme-linked immunoassay</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">Khushiramani R., Tuteja U., Shukla J., Batra H.V.
