Figure Lengend Snippet: Photograph of the transfected CHO-s cells obtained with a fluorescence microscope,at magnification of 10X, and the rate of transfection obtained with flow cytometry,24 h after transfection. (A) Untransfected CHO-s cells, (B) CHO-s cells transfected with pCEP4-hFIX wt , (C) CHO-s cells transfected with pCEP4-hFIX K22N , (D) CHO-s cells transfected with pCEP4-hFIX R37N plasmids
Article Snippet: Following Nhe I /Not I digestion, the target fragments, comprising the coding sequences of either the hFIX or its mutants and IRES-EGFP sequence, were subcloned into the pCEP4 expression vector (Thermo Fisher Scientific, USA), downstream to the cytomegalovirus (CMV) immediate early promoter/enhancer to end up with three bicistronic recombinant plasmids namely; pCEP4-hFIX wt , pCEP4-hFIX K22N , and pCEP4-hFIX R37N .
