Исследованы особенности измерения и расчета биологической активности эритропоэтинов с различным уровнем гликозилирования в тестах in vivo и in vitro. Диапазоны линейного ответа клеточной линии на эритропоэтин и его гипергликозилированный аналог отличались и составляли (0,39-0,56 нг/мл) и (3,1-12,5 нг/мл) соответственно. Проведенный анализ полученных результатов показывает возможность применения клеточного теста для сопоставления и количественной оценки активности аналогов эритропоэтина в международных единицах стандарта биологической активности (МЕ), принятых для эритропоэтина.</p></abstract><trans-abstract xml:lang="en"><p>The method for the assessment of biological activity of erythropoietin preparations in vitro on TF-1 sensitive cells culture has been developed. The special characteristics of measurements and calculations of the biological activity of erythropoietin with different levels of glycosylation in vivo and in vitro. Linear response ranges for cell lines to erythropoietin and its hyperglycosylated analogue differ and make (0.39-0.56 ng/ml) and (3.1-12.5 ng/ml), respectively. The results have shown the possibility of using cellular test for comparing and assaying the activity of erythropoietin analogues in standard international units of biological activity (IU) set for erythropoietin.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биологическая активность</kwd><kwd>эритропоэтин</kwd><kwd>дарбэпоэтин</kwd><kwd>клеточная линия TF-1</kwd><kwd>пролиферативный ответ</kwd><kwd>biological activity</kwd><kwd>erythropoietin</kwd><kwd>darbepoetin</kwd><kwd>cell line TF-1</kwd><kwd>proliferative response</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">Bunn HF.
