Изучение влияния активатора, окислителя и деблокирующего раствора на количественный выход олигонуклеотидов при производстве тест-системы для выявления ДНК Vibrio cholerae (ctxA+) методом полимеразной цепной реакции «ГенХол».</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В качестве объекта исследований были выбраны праймеры ctx2 и ctx3, входящие в состав «Тест-системы для выявления ДНК Vibrio cholerae (ctxA+) методом полимеразной цепной реакции «ГенХол». Для проведения исследований использовали экспериментальные составы растворов для деблокирования, активатора и окислителя и «стандартные» растворы, рекомендованные производителем ООО «Биоссет». Специфическую активность синтезированных праймеров ctx2 и ctx3 проверяли с использованием трех штаммов V. cholerae 569B, M-1298, 158 и E. coli 12226 О-55, готовили бактериальную суспензию возбудителей с конечной концентрацией 1·103 – 1·101 м.к./мл. ДНК выделяли методом нуклеосорбции в присутствии гуанидинизотиоцианата.</p></sec><sec><title>Результаты и вывод</title><p>Результаты и вывод. Показана возможность оптимизации производства генодиагностических препаратов путем увеличения выхода олигонуклеотидов при фосфорамидитном синтезе за счет использования в качестве деблокирующего раствора 3 % дихлоруксусной кислоты в дихлорметане и окислителя – 0,1 М раствор йода в уксусной кислоте и пиридине в соотношении 1:9. Применение таких реагентов увеличивает выход конечного продукта (праймеров) на 6 и 95 % соответственно. Использование усовершенствованной технологии синтеза позволит снизить затраты на дорогостоящие импортные реагенты и повысить количество выпускаемых генодиагностических препаратов для детекции особо опасных патогенов.</p></sec></abstract><trans-abstract xml:lang="en"><p>Objective of the study is to investigate the impact of activator, oxidize, and unblocking solution on the quantitative yield of oligonucleotides during manufacturing of the test-system for Vibrio cholerae (ctxA+) DNA detection “GenChol”, using polymerase chain reaction.</p><sec><title>Materials and methods</title><p>Materials and methods. The subject of the study is ctx2 and ctx3 primers, incorporated in the test-system “GenChol”. Utilized have been experimental formulations of solutions for unblocking, activator, and oxidizer and “standard” solutions, recommended by the manufacturer “BioSet” Ltd. Specific activity of the synthesized primers ctx2 and ctx3 has been evaluated on three different strains: V. cholerae 569B, M-1298, 158 and E. coli 12226 O-55. Bacterial suspension from the pathogen with final concentration of 1·103 – 1·101 m.c./ml has been produced. The DNA has been isolated applying nucleo-sorption in presence of guanidinium isothiocyanate.</p></sec><sec><title>Results and conclusions</title><p>Results and conclusions. Demonstrated is the possibility of optimization of diagnostic preparation production via increment of oligonucleotide yield in the process of phosphoramide synthesis, due to application of 3% dichloroacetic acid in dichloromethane as unblocking solution and oxidizer – 0.1 M iodine in athetic acid and pyridine in the ratio of 1:9. Utilization of such reagents increases the yield of the end product (primers) by 6 and 95 %, respectively. Enhanced technology for oligonucleotide synthesis will provide for the reduction of costs, associated with expensive imported reagents and the raise in the numbers of gene-diagnostic preparations for the detection of particularly dangerous pathogens.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>синтез олигонуклеотидов</kwd><kwd>деблокирование</kwd><kwd>активация</kwd><kwd>окисление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oligonucleotide synthesis</kwd><kwd>unblocking</kwd><kwd>activation</kwd><kwd>oxidation</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">А ралов А.
