Проведена функциональная оценка сорбционных качеств экспериментальных образцов сорбентов и их селективности к подклассам IgG. Обнаружено, что все сорбенты имеют хорошие характеристики по удалению IgG из биологических жидкостей, но сорбент на основе Phe-Trp-DTyr эффективней остальных связывает общий IgG. По отношению к подклассам IgG лучшие результаты связывания следующие: Phe-Gln-Tyr-OMe - IgG1(86,53 %), Phe-Ala-Tyr - IgG2(60,2 %), Phe-Trp-DTyr - IgG3 (59,52 %) и IgG4 (55,05 %).</p></abstract><trans-abstract xml:lang="en"><p>Biospecific sorbents for the removal of IgG and subclasses from biological fluids based on oligopeptides that contain aromatic protein residues have been created. A functional assessment of high-quality experimental samples of sorbents and their preferences for IgG subclasses was carried out. It was found that each sorbent has good characteristics for removing IgG from biological fluids, but the sorbent based on Phe-Trp-DTyr is more effective in binding of total IgG. With respect to IgG subclasses, the best binding results are as follows: Phe-Gln-Tyr-OMe - IgG1 (86,53%), Phe-Ala-Tyr - IgG2 (60,2%), Phe-Trp-DTyr - IgG3 (59,52%) and IgG4 (55,05%).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сорбция</kwd><kwd>сорбенты</kwd><kwd>иммуноглобулины</kwd><kwd>подклассы</kwd><kwd>белки</kwd><kwd>лиганды</kwd><kwd>пептиды</kwd><kwd>селективность</kwd><kwd>сорбционная емкость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sorption</kwd><kwd>sorbents</kwd><kwd>immunoglobulins</kwd><kwd>subclasses</kwd><kwd>proteins</kwd><kwd>ligands</kwd><kwd>peptides</kwd><kwd>selectivity</kwd><kwd>sorption capacity</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">Serum IgG subclasses in autoimmune diseases / H.
