FIGURE 3.

Comparison of uni- and bipolar electroporation in ECV304 cells. (A) Loading efficiency for 6-CF electroporation in function of the electric field strength. The three star symbols indicate a significant difference with p < 0.001 compared with all other bars in this graph; n = 13 for unipolar and 12 for bipolar electroporation. (B) Cell death in function of electric field strength, as determined with trypan blue. Stars indicate significances compared with all the other unipolar data (other significant differences are given in the text); n = 16 for unipolar and 12 for bipolar electroporation. (C) Size of the electroporation-loaded cell zone in function of electric field strength. The star symbol represents a significant difference with p < 0.05 compared with all bipolar data; n = 13 for both uni- and bipolar electroporation.
