Проведен выбор оптимального типа микро- и ультрафильтрационных мембран для использования в технологическом процессе. Исследованы свойства В-субъединицы холерного токсина, полученного по разработанной технологии. Разработанный способ масштабированного получения В-субъединицы холерного токсина делает процесс более технологичным за счет внедрения метода тангенциальной микро- и ультрафильтрации на этапах его очистки и концентрирования позволяет исключить трудоемкие операции хроматографической очистки и сохранить свойства В-субъединицы. Проведенные исследования позволяют получать В-субъединицу холерного токсина в производственных условиях с характеристиками, аналогичными при разработке технологии, и использовать ее в качестве компонента холерной химической вакцины.</p></abstract><trans-abstract xml:lang="en"><p>Consideration is given to implementation of state-of-the-art filtration technologies for up-scaled manufacturing of cholera toxin B-subunit, produced by recombinant Vibrio cholerae non O1 KM93 strain. Selected are micro- and ultra-filtration membranes to be incorporated into manufacturing method. Investigated are the properties of cholera toxin B-subunit, obtained applying the pilot technology. The engineered method for up-scaled manufacturing of cholera toxin B-subunit makes the procedure easier-to-maintain due to tangential micro- and ultra-filtration, performed at the stage of purification and concentration. It excludes labor-consuming chromatographic purification, while retaining B-subunit properties. The studies undertaken make it possible to manufacture cholera toxin B-subunit with the same characteristics as in the case of the pilot technology, but under production conditions, and use it as a component for chemical cholera vaccine.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>В-субъединица холерного токсина</kwd><kwd>тангенциальная фильтрация</kwd><kwd>свойства</kwd><kwd>cholera toxin B-subunit</kwd><kwd>tangential filtration</kwd><kwd>properties</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">Брахт К., Каталевский Е.Е., Савельева С.П.
