Sensitivity of in vivo luminescence measurements and dose effect. Values are mean +/- SEM of the integrated values of luminescence in ROI of the tibial cranial muscle 6 h (n = 6 to 10), 1 day and 8 days (n = 10 to 20) after electrotransfer of 0.3 μg (white columns), 3 μg (clear grey columns) and 30 μg (dark grey columns) of pCMV-luc+ into the tibial cranial muscle. For all points, background luminescence was subtracted. Statistical significance of the differences **** p < 0.0001, ** p < 0.01, * p < 0.05.
