Figure 1.

Hematocrit of β-thalassemic mice electrotransfered twice with 2, 4 and 6 μg of Epo plasmid. Hematocrit kinetics of β-thalassemic mice electrotransfered at day 0 and day 25 with 2 μg (cross), 4 μg (empty square) and 6 μg (solid square) Epo plasmid doses. The negative control (solid diamond) was realised by intramuscular injection of NaCl (150 mM) followed by electric pulse application. Error bars show standard error of mean (SEM). Arrows indicate electrotransfer applications.
