Abstract

Prezenta invenţie se referă la biotehnologie, industria medico-biologică, medicină şi în special, la ADN clonaţi, care codifică eritropoietina umană, expresiile ADN indicate şi la obţinerea in vitro a eritropoietinei umane active.Se descrie clonarea fragmentelor ADN genom din ficatul fetal uman şi fragmente ale ADNc, care asigură nivele excepţional de înalte ale expresiei eritropoietinei în celulele de mamifere, a fost obţinută linia de celule ovariene de hamster chinezesc CHO, care produce EPO recombinantă (CHO EPO Cla 4a4.02-7). Ca rezultat al expresiei fragmentelor clonate ale ADN în celulele de mamifere s-a obţinut EPO O-glicosilată cu o activitate specifică de cel puţin 200000 unităţi/mg şi compoziţia farmaceutică, în care se utilizează EPO recombinantă menţionată în calitate de ingredient activ.Rezultatul invenţiei constă în creşterea nivelelor de expresie in vitro a eritropoietinei umane active, precum şi în înlăturarea reacţiilor adverse în timpul tratamentului cu eritropoietină recombinantă umană.
