Современные методы анализа слезной жидкости включают хроматографию и масс-спектрометрию, что обеспечивает высокую точность идентификации и количественное определение белков, являясь незаменимыми инструментами для изучения протеома. Целью настоящего исследования явилось изучение белкового состава слезной жидкости с помощью масс-спектрометрии у 5 добровольцев в норме, выявление основных компонентов и уникальных белков, а также анализ их значимости для диагностики и терапии офтальмологических заболеваний.</p></abstract><trans-abstract xml:lang="en"><p>The protein composition of lacrimal fluid changes in various pathological conditions, making it a promising biomarker for the diagnosis of ophthalmic and systemic diseases. Modern methods of lacrimal fluid analysis include chromatography and mass spectrometry, which ensure highly accurate identification and quantification of proteins, serving as indispensable tools for proteome studies. The aim of this study was to investigate the protein composition of lacrimal fluid using mass spectrometry in 5 healthy volunteers, identify the main components and unique proteins, and analyze their significance for the diagnosis and treatment of ophthalmic diseases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>слезная жидкость</kwd><kwd>белки</kwd><kwd>протеомный анализ</kwd><kwd>масс-спектрометрия</kwd><kwd>диагностика</kwd><kwd>офтальмопатология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lacrimal fluid</kwd><kwd>proteins</kwd><kwd>proteomic analysis</kwd><kwd>mass spectrometry</kwd><kwd>diagnostics</kwd><kwd>ophthalmopathology</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">никто из авторов не имеет финансовой заинтересованности в представленных материалах или методах</funding-statement><funding-statement xml:lang="en">no author has a financial or property interest in any material or method mentioned</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">MaJ YW, Utheim TP, Reppe S, Galtung HK, Aass HC, Eriksen HO.
