По этой причине каждую серию вакцинного сырья исследуют на определение концентрации 146S компонента. В статье представлены результаты изучения применения спектрометрического метода для определения концентрации полных частиц при оценке количества РНК вируса ящура, выделенной после иммунного захвата. Данный способ является дешевым, простым в исполнении, позволяет определять концентрацию 146S частиц вируса ящура в неинактивированной культуральной суспензии. Выявлено существование зависимости между концентрацией 146S частиц и количеством молекул РНК, выделенных из вирионов после их штаммоспецифического иммунного захвата и количественно детектированных спектрометрическим методом. Представленный метод позволяет определять значение концентрации 146S компонента вируса ящура в неинактивированном сырье для вакцины с применением предложенной линейной модели. Корреляция спектрометрического способа с полимеразной цепной реакцией с обратной транскрипцией в режиме реального времени и реакцией связывания комплемента при тестировании 360 неинактивированных суспензий вируса ящура всех типов составила 94,5–99,5%. Для положительного контроля совпадение фактических и ожидаемых результатов соответствовало 99,0–99,6%. В отрицательном контрольном образце геном и 146S частицы вируса ящура не обнаружены, что соответствовало ожиданиям.</p></abstract><trans-abstract xml:lang="en"><p>During FMD vaccine production, special attention is paid to the concentration of 146S particles bearing the critical biological features of FMDV and being the main components that have an effect on vaccine immunogenicity. For this reason, each batch of vaccine raw material is tested for 146S component concentration. The paper presents the results of the use of a spectrometric method for whole particle concentration determination during quantification of FMDV RNA extracted after immune capture. It is an inexpensive, easy-to-perform method allowing for determination of FMDV 146S particle concentration in the non-inactivated culture suspension. 146S particle concentration was found to depend on the number of RNA molecules extracted from virions after their strain-specific immune capture and quantitatively detected by the spectrometric method. The presented method allows for determination of 146S component concentration in the non-inactivated vaccine raw material using the proposed linear model. The spectrometric method showed 94.5–99.5% correlation with real time reverse transcription polymerase chain reaction and complement fixation test based on the results of tests of 360 non-inactivated suspensions of FMDV of all types. Tests of the positive control demonstrated 99.0–99.6% compatibility of actual and expected results. FMDV genome and 146S particles were not detected in the negative control, and that was in line with expectations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>РНК вируса ящура</kwd><kwd>концентрация 146S компонента</kwd><kwd>спектрометрический анализ</kwd><kwd>иммунный захват</kwd></kwd-group><kwd-group xml:lang="en"><kwd>FMDV RNA</kwd><kwd>146S component concentration</kwd><kwd>spectrometric analysis</kwd><kwd>immune capture</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет средств ФГБУ «ВНИИЗЖ» в рамках тематики научно-исследовательских работ «Ветеринарное благополучие».</funding-statement><funding-statement xml:lang="en">The study was funded by the FGBI “ARRIAH” within the framework of “Veterinary Welfare” research work.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Foot and mouth disease (infection with foot and mouth disease virus).
