Abstract

Изобретение частично основано на наблюдении того, что окислительный фермент из клеток CHO, в частности QSOX1, может переносить, по-видимому, способ жесткой очистки антитела со снижением эффективности последующей конъюгации антитела с лекарственным средством. Перенесет ли окислительный фермент очистку, зависит от того, какие способы очистки используют, что может варьироваться от одного антитела к другому. Зная, что загрязнение окислительным ферментом из клеток CHO является потенциальной проблемой для последующей конъюгации, для любого антитела можно разрабатывать подходящую схему очистки, устраняющую или, по меньшей мере, снижающую окислительные ферменты из CHO до приемлемого уровня.
