Figure 10: Percentage of bacterial plasmid forms (a) and photograph (b) of neutral agarose gel after electrophoresis of pBSK plasmids exposed to lowlevel red laser in 2.5 Hz pulsed emission mode and incubated with exonuclease III. Lanes: (1) pBSK; (2) pBSK+exonuclease III; (3) pBSK+pulsed laser 0.13 J; (4) pBSK+pulsed laser 0.13 J+exonuclease III; (5) pBSK+pulsed laser 0.52 J; (6) pBSK+pulsed laser 0.52 J+exonuclease III; (7) pBSK+pulsed laser 1.04 J; (8) pBSK+pulsed laser 1.04 J+exonuclease III. (□) SC (supercoiled); (■) OC (open circle). Numbers (1) through (8) for the histogram refer to gel lanes. Error bars indicate the standard deviation of the mean for n=3 independent experiments.
