Changes in erythropoietin (Epo) levels after repeated muscular electrotransfer of 1 μg and 1.5 μg of Epo-plasmid. the data provided shows the mean EPO level reached in mice following the electrotransfer treatments, for all three groups of mice (ie, control group, 1 μg treated group and 1.5 μg treated group). Mouse Epo changes in β-thalassemic mice electrotransfered with NaCl 150 mM solution for control group (solid diamond) or with 1 μg (solid sphere) and 1.5 μg (solid square) Epo-plasmid doses for the other groups. Electrotransfer was performed at day 0, 34, 112 and 215 for the three groups. One additional electrotransfer was performed at day 77 for the 1 μg group. Arrows indicate electrotransfer applications. The EPO ELISA Medac^™kit was used to measure mouse Epo based on cross-reaction (detection limit of 25 mU/ml for human Epo). Data are presented as mean Epo levels with standard error of the mean (SEM).
