В соответствии с международными и  отечественными требованиями содержание остаточной ДНК штамма-продуцента в подобных  препаратах не должно превышать 10 нг на 1 дозу, для препаратов, предназначенных для  частого или длительного введения, эта величина не должна превышать 100 пг на 1 дозу. В  статье представлено описание наиболее часто используемых методов определения  содержания остаточной ДНК штамма-продуцента в субстанциях биотехнологических препаратов: молекулярная гибридизация с биотиновой или  дигоксигениновой меткой ДНК-зонда (полуколичественный метод), система Threshold, ПЦР в  режиме реального времени, метод с флуоресцентным реагентом (количественные  методы). В случае использования методов с флуоресцентным реагентом или ПЦР в режиме  реального времени для замены ранее использовавшегося метода требуется подтверждение  их правильности, например с помощью сравнительной оценки содержания остаточной ДНК  двумя методами — вновь вводимым и ранее использовавшимся методом. Отмечены  преимущества и недостатки методов, источники неопределенности результатов при  проведении испытаний, указана необходимость использования стандартных и контрольных  образцов, аттестованных в установленном порядке. В субстанциях, внесенных в  Государственный реестр лекарственных средств, содержание остаточной ДНК штамма-продуцента соответствует международным рекомендациям.</p></abstract><trans-abstract xml:lang="en"><p>Biotechnological products manufactured by recombinant DNA technology are widely used nowadays. According to the national and  international requirements the amount of residual host cell DNA in  such products should not exceed 10 ng per dose. However, for  products intended for frequent or long-term use, this amount must  not exceed 100 pg per dose. This article describes methods most  frequently used for quantification of residual host cell DNA in  biological active substances contained in biotechnological products:  molecular hybridization with biotin- or digoxigenin-labelled DNA- probes (semiquantitative method), Threshold system, real-time PCR, method based on the use of a fluorescent reagent (assays). If  a method based on the use of a fluorescent reagent or real-time PCR are used to replace the current procedure, it is necessary to  demonstrate their validity, e.g. by comparing the results of residual DNA quantification obtained by the two methods — the new one and the current one. The article dwells upon the advantages and  disadvantages of the methods and potential sources of uncertainty.  It highlights the importance of using appropriately certified reference standards and retention samples. The biological active substances  included into the State Register of Medicinal Products conform to the international requirements in terms of the amount of residual host cell DNA.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биотехнологические препараты</kwd><kwd>остаточная ДНК штамма-продуцента</kwd><kwd>рекомбинантные белки</kwd><kwd>молекулярно-биологические методы контроля</kwd><kwd>стандартные и контрольные образцы</kwd><kwd>полимеразная цепная реакция (ПЦР)</kwd><kwd>метод молекулярной гибридизации</kwd><kwd>система Threshold</kwd><kwd>метод с флуоресцентным реагентом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biotechnological products</kwd><kwd>residual host cell DNA</kwd><kwd>recombinant proteins</kwd><kwd>molecular-biological methods of quality control</kwd><kwd>polymerase chain reaction (PCR)</kwd><kwd>molecular hybridization method</kwd><kwd>Threshold system</kwd><kwd>method based on the use of a fluorescent reagent</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">Общая фармакопейная статья 1.7.1.0007.15 Лекарственные средства, получаемые методами рекомбинантных ДНК.
