Для стабилизации основных свойств жидких форм эритроцитарных диагностических препаратов в настоящее время необходима разработка технологии получения лиофилизированных форм диагностикумов, которая позволит сохранить первоначальные свойства препарата в течение длительного времени. Цель работы: разработка защитной среды высушивания и режима лиофилизации для стабилизации диагностикума эритроцитарного туляремийного иммуноглобулинового. Материалы и методы: были использованы вспомогательные вещества для подготовки защитных сред (желатин, тиомочевина, трегалоза, сахароза, декстран, твин 80). Для контроля чувствительности и специфичности лиофилизированных диагностикумов использовали 9 штаммов гомологичных и гетерологичных микроорганизмов разных родов и видов. При изучении стабильности основных показателей качества препаратов для диагностики in vitro (внешний вид высушенного препарата; потеря в массе при высушивании; растворимость, внешний вид восстановленного препарата; внешний вид препарата после отстаивания; чувствительность; специфичность) учитывали температуры различных климатических зон, в которых предполагается их реализация и использование. Результаты: разработаны и использованы стабилизирующие защитные среды с различным составом, с последующей сублимационной сушкой препарата и постановкой контрольных исследований. Наиболее перспективной признана среда высушивания для эритроцитарных диагностикумов, содержащая в своем составе меньшее количество ингредиентов — 6% декстрана, 0,06% твин 80 и азид натрия до 0,01%, как наиболее простая в исполнении и обеспечивающая полное сохранение качественных показателей препарата. Отработан рентабельный 12–14-часовой режим лиофилизации. Выводы: по совокупности полученных результатов изучения стабильности в реальном времени (долговременная стабильность) и ускоренном исследовании стабильности лиофилизированных форм диагностикума показана возможность хранения в течение двух лет при регламентированной температуре от 2 до 8 °С, а также в условиях повышенных и пониженных температур при 30±2 °С и минус 18 °С соответственно. Отрицательного влияния указанных температур на результаты контролируемых показателей не выявлено.</p></abstract><trans-abstract xml:lang="en"><p>Liquid erythrocyte diagnostic preparations have a practical disadvantage; i.e., long-distance transportation involving possible non-compliance with cold-chain requirements may result in a complete loss of biological activity. A lyophilisation technology is necessary to ensure that the preparations retain their original properties for a long time. The aim of the work was to develop a protective medium and conditions for lyophilisation to stabilise the erythrocyte diagnostic preparation of tularaemia immunoglobulin. Materials and methods: Gelatin, thiourea, trehalose, sucrose, dextran, and Tween 80 were used as excipients for protective media. The authors used nine strains of homologous and heterologous microorganisms of different genera and species to control the lyophilised diagnostic preparation sensitivity and specificity. Evaluation of the main stability-related quality attributes (appearance of the dried preparation, loss on drying, solubility, appearance after reconstitution, appearance after settling, sensitivity, specificity) considered the temperatures specific to the climatic zones where the in vitro diagnostics is intended to be marketed and used. Results: The authors developed protective stabilising media with different compositions, used them in freeze-drying of the preparation and carried out control testing. The most promising was the lyophilisation medium containing a smaller amount of ingredients —6% of dextran, 0.06% of Tween 80 and up to 0.01% of sodium azide—as it was the simplest one to prepare and ensured complete preservation of the quality attributes. The authors carried out practical evaluation of lyophilisation procedures, and the 12–14-hour procedure proved to be the most cost-effective. Conclusions: The results of long-term, or real time, and accelerated stability testing of the lyophilised diagnostic preparation demonstrated the possibility of two-year storage at a labelled temperature of 2–8 °C, as well as at elevated and low temperatures of 30±2 °С and –18 °С, respectively. The tests showed no negative effects of the temperatures on the controlled quality attributes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>туляремия</kwd><kwd>среда высушивания</kwd><kwd>стабильность препаратов</kwd><kwd>реакция непрямой гемагглютинации</kwd><kwd>лиофилизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tularaemia</kwd><kwd>lyophlisation medium</kwd><kwd>stability</kwd><kwd>indirect hemagglutination test</kwd><kwd>lyophilisation</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">Ираклионова НС, Сысуев ЕБ, Мась ЕС.
