Для унификации методики с использованием клеточной культуры, позволяющей оценивать специфическую активность филграстима, важен выбор одного из красителей, используемых для окрашивания клеток. Цель работы: сравнительное изучение красителей тетразолиевого и резазуринового рядов в испытаниях по определению способности филграстима активировать пролиферацию чувствительных клеток. Материалы и методы: использовали клеточную линию NFS-60 (клетки миелолейкоза мышей), 2-й Международный стандарт гранулоцитарного колониестимулирующего фактора (МСО), красители МТТ, MTS, WST-1, alamarBlue. Оценку пролиферативной активности клеток проводили в условиях in vitro. Уровень пролиферации клеток учитывали по интенсивности флуоресценции или абсорбции. Статистическую обработку результатов проводили с помощью программы Origin Pro 9.1. и приложения Microsoft Excel. Результаты: приведена сравнительная характеристика наиболее часто используемых красителей. Описана процедура выбора оптимальных условий проведения испытания с некоторыми из изучаемых красителей. Для анализа потенциальной возможности влияния на конечный результат рассмотрены такие факторы, как продолжительность инкубации клеточной суспензии с МСО и с красителем, состав лизирующего буфера (для окрашивания с помощью МТТ) и различные режимы считывания. Несмотря на то что все изученные красители в заданных условиях испытания позволили получить воспроизводимые кривые «доза–эффект», значения 50% эффективных концентраций статистически значимо не отличались только между испытаниями с использованием трех красителей: МТТ, MTS и alamarBlue (р &gt; 0,05). Выводы: лучшая воспроизводимость результатов была получена в испытаниях с использованием МТТ и alamarBlue. Более простая и менее продолжительная процедура испытания с alamarBlue, отсутствие стадии лизиса клеток и необходимости применения дополнительных реагентов позволяет рекомендовать этот краситель для унификации методики, проводимой в связи с разработкой проекта общей фармакопейной статьи.</p></abstract><trans-abstract xml:lang="en"><p>Assessment of specific activity of Russian and foreign-made filgrastim products by biological in vitro methods is performed using different types of dyes. It is important to choose one cell staining dye in order to align the procedure of filgrastim specific activity assessment using cell culture. The aim of this study was to perform comparative assessment of tetrazolium and resazurin dyes in tests determining filgrastim ability to activate proliferation of sensitive cells. Materials and methods: NFS-60 (mouse myelogenous leukemia) cell line, 2nd International Standard for Granulocyte Colony Stimulating Factor (IS), as well as МТТ, MTS, WST-1, and alamarBlue dyes were used in the study. Proliferative activity of cells was assessed in vitro. The level of cell proliferation was assessed by fluorescence or absorbance intensity. Origin Pro 9.1. and Microsoft Excel applications were used for statistical processing of the obtained results. Results: the paper compares characteristics of the most widely used dyes. It describes the procedure for choosing optimal test conditions for some of the studied dyes. The authors analysed the potential of some factors, such as duration of cell suspension incubation with IS and with a dye, composition of the lysis buffer (for MTT staining), and different readout modes, to influence the final results. Despite the fact that all the studied dyes gave reproducible dose–response curves under the given test conditions, 50% effective concentrations showed no statistically significant differences in tests with only three dyes: МТТ, MTS, and alamarBlue (р &gt; 0.05). Conclusions: better reproducibility of results was obtained in tests using МТТ and alamarBlue. The test procedure using alamarBlue is easier to perform and less time-consuming, it does not include the cell lysis stage and does not require additional reagents, therefore this dye may be recommended for harmonisation of the test procedure to be elaborated for the Russian Pharmacopoeia.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>анализ пролиферации клеток</kwd><kwd>МТТ-тест</kwd><kwd>специфическая биологическая активность филграстима</kwd><kwd>соли тетразолия</kwd><kwd>alamarBlue</kwd><kwd>резазурин</kwd><kwd>MTS</kwd><kwd>WST-1</kwd><kwd>клеточная линия NFS-60</kwd><kwd>гранулоцитарный колониестимулирующий фактор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cell proliferation assay</kwd><kwd>МТТ test</kwd><kwd>filgrastim specific biologival activity</kwd><kwd>tetrazolium salts</kwd><kwd>alamarBlue</kwd><kwd>resazurin</kwd><kwd>MTS</kwd><kwd>WST-1</kwd><kwd>NFS-60 cell line</kwd><kwd>granulocyte colony stimulating factor</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания ФГБУ «НЦЭСМП» Минздрава России № 056-00003-20-00 на проведение прикладных научных исследований (номер государственного учета НИР АААА-А18-118021590049-0).</funding-statement><funding-statement xml:lang="en">The study reported in this publication was carried out as part of a publicly funded research project No. 056-00003-20-00 and was supported by the Scientific Centre for Expert Evaluation of Medicinal Products (R&amp;D public accounting No. АААА-А18-118021590049-0).</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">Аникина ЛВ, Пухов СА, Дубровская ЕС, Афанасьева СВ, Клочков СГ.
