Клеточные стенки дрожжей солюбилизированы путем частичного гидролиза в муравьиной кислоте при обработке ультразвуком и температуре ≈100 °С. Добавкой лизата клеточных стенок дрожжей в сшиваемый раствор ПВС и последующей обработкой разбавленным лизатом микросферы функционализованы как мишени для фагоцитоза. Получены флуоресцентные микросферы при использовании в качестве дисперсионной среды изооктана с добавками ПАВ Span 85 и Tween 85, насыщенного флуорохромами – производными 2-аминопиримидина. Разработана методика оценки фагоцитарной активности лейкоцитов с применением функционализованных таким образом ММС.</p></abstract><trans-abstract xml:lang="en"><p>Microspheres comparable with yeast cells in size were obtained by the glutaraldehyde crosslinking of polyvinyl alcohol (PVA), whose 25 g/l water solution containing magnetite particles was dispersed in the isooctane/Span 85/Tween 85 medium. yeast cell walls were partially hydrolysed by sonication in formic acid near the boiling point. The microspheres were made targets for phagocytosis by the addition of yeast lysate to the crosslinkable PVA solution and a subsequent treatment of the freshly crosslinked microspheres with diluted yeast lysate. The microspheres were also made fluorescent when the emulsification medium saturated with fluorescent 2-aminopyrimidine derivatives was used. A protocol for phagocytosis assay using the thus modified microspheres was developed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микросферы</kwd><kwd>дрожжи</kwd><kwd>фагоцитоз</kwd><kwd>поливиниловый спирт</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microspheres</kwd><kwd>yeasts</kwd><kwd>phagocytosis</kwd><kwd>polyvinyl alcohol</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">Колісник, Н.
