Viability of H69 and SW780 cells after calcium electroporation.

<p>Viability, assessed using MTS assay, of H69, a human small cell lung cancer cell line (<b>A</b>); and SW780, a human bladder cancer cell line (<b>B</b>) 24 hours after treatment with calcium electroporation. Final extracellular calcium concentrations of 0 mM, 1 mM, 3 mM, or 5 mM and applied electric field of either 0.8 kV/cm, 1.0 kV/cm, or 1.2 kV/cm. Cells thrice thawed and frozen, then sonicated were used as control (dead cells). Results are illustrated as percentage of control (no electroporation, no added calcium), electroporation (EP), mean + S.D., n = 6.
