Non-invasive measurement of electrical currents at tumors ex vivo. (a) Cell Line Derived Tumor Allograft (CDA) Mouse Model (b) Schematic drawing of the electrical current measurement using vibrating probe. (c) Representative measurements of the outward and inward currents. (d) Measurements made at four cardinal points of the tumor surface. Three replicate measurements were made at each point, data are shown as mean ± SEM of each point.
