Electrode for EVOM ® Manual with Replaceable Blades Ensures Stable Measurements
The STX4 electrode is the most recent version of chopstick electrode for the EVOM ® Manual (or the older version, EVOM3), and it is designed to facilitate measurements of voltage (potential difference: PD) and resistance (transepithelial electrical resistance: TEER) of cultured epithelia (cellular layer) grown onto permeable membrane inserts in 12- and 24-well tissue culture plates. STX4 can measure directly inside the well plates with 12 and 24 inserts. The STX4 is designed primarily for 24-well hanging inserts or transwells (e.g., Corning 3470), and the electrode¿s best performance can be seen in this format.
