(EN) EXPRESSING SYSTEM
(RU) ЭКСПРЕССИРУЮЩАЯ СИСТЕМА
Abstract
(EN) FIELD: medicine. SUBSTANCE: invention concerns the method for making an immunogenic reagent which causes immune response on infection Bacillus anthracis, including one to several polypeptides which together represent three domains of a full-size protective antigen (PA) from B anthracis or their versions, and at least, one of specified domains contains domain 1 or domain 4 of the PA, or its version. Said polypeptides of specified immunogenic reagent, and the full-size PA are produced as a result of expression in a recombinant cell E.coli. The invention also discloses an expression vector and nucleic acid with percent of residual guanidine and cytosine more than 35%, coding immunigenic polypeptide which is said protective antigen (PA). EFFECT: high-yield immunogenic polypeptide. 13 cl, 5 dwg, 3 tbl, 6 ex
(RU) Изобретение касается способа получения иммуногенного реагента, который вызывает иммунный ответ на инфекцию Bacillus anthracis, включающего в себя один или несколько полипептидов, которые вместе представляют три домена полноразмерного защитного антигена (РА) из В. anthracis или их варианты, и по меньшей мере один из указанных доменов включает в себя домен 1 или домен 4 РА или его вариант. Данные полипептиды указанного иммуногенного реагента, а также полноразмерный РА продуцируются в результате экспрессии в рекомбинантной клетке E.coli. Изобретение раскрывает также вектор экспрессии и нуклеиновую кислоту с процентной долей остатков гуанидина и цитозина более 35%, кодирующую иммуногенный полипептид, являющийся защитным антигеном (РА). Использование данного способа обеспечивает высокий выход иммуногенного полипептида. 4 н. и 9 з.п. ф-лы, 5 ил., 4 табл.
