Для изготовления микрочипа на подложке иммобилизируют белковые молекулы. Одним из самых распространенных и доступных типов подложек является стекло, однако, поскольку стеклянная поверхность не содержит функциональных групп, которые обеспечивали бы надежное связывание с белками, требуется ее модификация.</p><p>Целью данной работы являлась разработка методики химической модификации стеклянной поверхности для изготовления белковых микрочипов. В процессе разработки методики варьировали следующие параметры: растворитель для 3-аминопропилтриэтоксисилана, время проведения реакции силанизации, концентрация глутарового альдегида, состав буфера для печати целевого белка (меченного флуорохромом аллофикоцианином анти-IgE человека) на модифицированную поверхность. Об эффективности иммобилизации белковых молекул судили по интенсивности флуоресценции спотов. В результате исследований установлено отсутствие влияния растворителя для 3-аминопропилтриэтоксисилана на эффективность иммобилизации целевого белка на модифицированной поверхности и определено оптимальное время проведения реакции силанизации ‒ 60 мин, а также показано, что оптимальная концентрация глутарового альдегида – 2,5 % (v/v), а оптимальный состав буфера для печати – фосфатно-солевой буфер с добавлением 4 % (v/v) глицерина. Предложенная методика обеспечивает эффективную иммобилизацию белков, что продемонстрировано на примере флуоресцентно-меченых антител. В дальнейшем планируется использовать данную методику для изготовления белковых микрочипов для аллергодиагностики c целью выявления специфических IgE в сыворотке крови пациентов.</p></abstract><trans-abstract xml:lang="en"><p>Protein microarray consists of a support (usually glass or polymer) and immobilized proteins (ferments, antibodies, etc.). Being one of the most widespread and accessible support material, glass still has a significant disadvantage: its surface doesn’t contain functional groups capable of bonding with proteins. Therefore, the glass surface needs to be modified in order to immobilize capture proteins.</p><p>The aim of this work was to develop a technique of chemical modification of the glass surface for fabrication of protein microarrays. In our study we varied the following experimental parameters: solvent for 3-aminopropyltriethoxysilane, time of silanization reaction, concentration of glutaraldehyde, composition of a buffer for printing the target protein (allophycocyanin-labelled human anti-IgE) on the modified surface. The efficiency of protein molecule immobilization was quantified using the intensity of spot fluorescence. As a result, it was shown that there was no influence of the solvent for 3-aminopropyl-triethoxysilane on the immobilization efficiency of the target protein on the modified surface, and the optimal time for the silanization reaction was 60 minutes. It was also shown that the optimal concentration of glutaraldehyde was 2.5 % (v/v) and the optimal composition of the printing buffer was phosphate-buffered saline with the addition of 4 % (v/v) glycerol.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микрочип</kwd><kwd>белки</kwd><kwd>поверхность</kwd><kwd>модификация</kwd><kwd>стекло</kwd><kwd>буфер</kwd><kwd>IgE</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microarray</kwd><kwd>proteins</kwd><kwd>surface</kwd><kwd>modification</kwd><kwd>glass</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках мероприятия 35 «Разработать тест-систему на основе технологии микрочипов для выявления IgE-зависимых аллергических реакций» подпрограммы 1 «Инновационные биотехнологии» Государственной программы «Наукоемкие технологии и техника» на 2021‒2025 годы.</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of activity 35 “Develop a test system based on microchip technology to detect IgE-dependent allergic reactions” of subprogram 1 “Innovative biotechnologies” of the State program “High-tech technologies and equipment” for 2021–2025.</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">Interferometric silicon biochips for label and label-free DNA and protein microarrays / M.
