Чистоту экстрагированных липополисахаридов оценивали методом ВЭЖХ-УФ. Пирогенную активность определяли с помощью Limulus Amebocyte Lysate-теста и использовали для мониторинга функциональности очищенных липополисахаридов. ВЭЖХ-анализ показал высокую степень чистоты, сравнимую с коммерческим липополисахаридом. Пирогенная активность подтверждала функциональную активность очищенных липополисахаридов. Представленный протокол может быть использован для выделения липополисахаридов с высокой чистотой и функциональной активностью. </p></abstract><trans-abstract xml:lang="en"><p>In this study, a procedure was applied to purify lipopolysaccharides from Escherichia coli based on a hot phenolic extraction protocol. The purity of the extracted lipopolysaccharides was assessed by HPLC-UV. Pyrogenic activity was determined using the Limulus Amebocyte Lysate test and used to monitor the functionality of the purified lipopolysaccharides. HPLC analysis showed a high degree of purity comparable to commercial lipopolysaccharide. Pyrogenic activity confirmed the functional activity of purified lipopolysaccharides. The presented protocol can be used to isolate lipopolysaccharides with high purity and functional activity. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>Escherichia coli</kwd><kwd>эндотоксин</kwd><kwd>экстракция</kwd><kwd>липополисахарид</kwd><kwd>очистка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Escherichia coli</kwd><kwd>endotoxin</kwd><kwd>extraction</kwd><kwd>lipopolysaccharide</kwd><kwd>purification</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">Erridge C., Bennett-Guerrero E., Poxton I.R.
