![]() ![]() The confluence of the cellular monolayer is quickly determined by a sharp increase in TEER. ![]() Recently there has been a significant surge of interest in introducing a combined electrode for resistance measurements in the Millipore 96-well PAMPA (parallel artificial membrane permeability assay) plate. TEER measurement technology, which was first introduced by WPI in the mid-1980’s, has since been perfected and expanded to include a range of TEER related manual and automatic instrumentation. Manual TEER measurements of epithelial cells in 6-, 12-, and 24-well plates.Electrically isolated meter that plugs into a standard outlet for continual readout without push buttons. ![]() STX2 manual electrodes and test electrode included with every meter.#EVOM WORLD NETWORK FILMS FREE#įree standing with tilt bail, making viewing results easy. TEER and trans-epithelial voltage measurements in 2D cell cultures.Ī variety of accessory electrodes are available for measuring TEER in 6- and 96-well fixed (HTS) and removable well culture systems (See STX100 series and Endohm electrodes).You can verify performance and calibrate the meter for TEER function using provided test resistor.Making TEER Measurements to Determine Cellular Confluence The EVOM was the first instrument designed specifically to perform routine Trans Epithelial Electrical Resistance (TEER) measurement in tissue culture research. EVOM2™ is the next generation, redesigned for ease of use. The EVOM2™ not only qualitatively measures cell monolayer health, but also quantitatively measures cellular confluence. The unique electronic circuit of the EVOM2™ and the included STX2 electrode detect the confluence of the cellular monolayer. Isolated battery power for 10 hours of use When combined with WPI’s Endohm chamber, the EVOM2™ can also be used to perform more accurate quantitative measurements or lower resistance measurements like transendothelial electrical resistance measurements. The isolated power source of the EVOM2™ was specifically designed to avoid adverse effects on tissue and the formation of electrode metal deposits, even when it is plugged into a standard wall outlet. Now, the EVOM2™ is always on when you need it. In addition, its rechargeable battery allows up to 10 hours of mobile use. The four-and-a-half digit readout provides a range of 1-9,999 Ω. The included test electrode lets you calibrate the resistance measurements for an accurate reading every time. ![]()
