Спектры флуоресценции полученных микросфер зависят от рН среды. Разработана методика оценки рН в интервале 4–9 по соотношению яркостей зеленого и красного каналов фрагментов цифровых изображений микросфер, полученных цветной камерой микроскопа. Микросферы практически не теряют флуорохромы в процессе хранения (180 дней) и могут применяться как индикаторы локального рН среды, в частности, при исследовании фагоцитоза.</p></abstract><trans-abstract xml:lang="en"><p>The fluorescent dyes 4,4′-(1E,1′Е)-2,2′-(2-aminopyrimidin-4,6-diyl) bis(ethene-2,l-diyl) bis(N,N-dimethylphenylamine) (АРМ) and 4′-(1E,1′Е)-2,2′-(2-aminopyrimidin-4,6-diyl) bis(ethene-2,l-diyl) bis(N,N-diethylphenylamine) (APE) were incorporated into glutaraldehyde-crosslinked polyvinyl alcohol microspheres containing magnetite. Fluorescence spectra of the obtained microspheres depend on pH of the medium. A technique for pH measurement within the range of 4–9 based on calculation of the green/red ratio of the fragments of color microimages of the microspheres was developed. only negligible loss of the fluorochromes from the microspheres occured during the storage time of 180 days. Thus the microspheres may be used as local pH indicators, e. g. for phagocytosis studies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микросферы</kwd><kwd>флуоресцентные красители</kwd><kwd>рН</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microspheres</kwd><kwd>fluorescent dyes</kwd><kwd>pH</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">pH sensing in living cells using fluorescent microspheres / M.
