Being naturally nontoxic, CRM197 is a promising adjuvant and ideal carrier protein for conjugate vaccines. Typically, production of diphtheria toxin and some of the non-toxic proteins are carried out by <italic>Corynebacterium diphtheriae</italic>. Production of recombinant protein CRM197 in <italic>Escherichia coli </italic>is advantageous. It is simple, cheap and permits production of the target protein in a short time using a non-pathogenic microorganism. In this study patented high-yield-producing <italic>E. coli </italic>strain was used. As a part of the study the following steps were taken: protocol adjustment for induction of <italic>crm197 </italic>gene, production and purification of recombinant CRM197 by ion-exchange, hydrophobic and gel-filtration chromatography. The purity of the final preparation reached 97%.</p></abstract><trans-abstract xml:lang="ru"><p>Белок CRM197 является нетоксичным производным дифтерийного токсина и характеризуется одной мутацией, а именно, заменой глицина на глутаминовую кислоту в положении 52. Белок CRM197 является перспективным адъювантом нового поколения, который может быть успешно использован в вакцинных и терапевтических препаратах. Классическим способом получения дифтерийного токсина и его нетоксичных производных является продукция в клетках <italic>Corynebacterium diphtheriae</italic>. Преимущество использования <italic>E. coli </italic>в качестве продуцента состоит в том, что данный метод является более простым и дешевым, и позволяет получать рекомбинантный CRM197 в короткие сроки с использованием непатогенного микроорганизма. В данной работе использовался запатентованный высокопродуктивный штамм-продуцент рекомбинантного CRM197 на основе клеток <italic>E. coli</italic>. В ходе исследования подобран оптимальный протокол индукции экспрессии гена <italic>crm197</italic>, разработан метод получения высокоочищенного препарата рекомбинантного CRM197 путем последовательного применения ионообменной, гидрофобной и молекулярноситовой типов хроматографии. </p></trans-abstract><kwd-group xml:lang="en"><kwd>recombinant protein</kwd><kwd>CRM197</kwd><kwd>adjuvant</kwd><kwd>conjugate vaccine</kwd><kwd>diphtheria toxin</kwd><kwd>Escherichia coli</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рекомбинантный белок</kwd><kwd>CRM197</kwd><kwd>адъювант</kwd><kwd>конъюгированные вакцины</kwd><kwd>дифтерийный токсин</kwd><kwd>Escherichia coli</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
