(TITLE: Corning 96, Corning Biocoat/Falcon 24, Corning Costar 24, Millipore 96) EndOhmĮndOhm cell culture cup chambers are built for stability and reproducibility to 1% tolerance. This is an excellent choice for 24- and 96-well plates. The size of the electrodes and the design reduces the chances of sample contamination. The design improves accuracy over the STX2 and STX3, and it is more durable, too. The STX HTS electrodes are designed for high throughput screening, because the tips are much smaller, and the electrode is keyed to fit neatly into the filter wells. The STX4 is designed for use with 24-well plates. This means you never need to chloride the tips, and you may replace the blades instead of the entire electrode. This electrode is the only one with replaceable blades. Its design offers greater precision when compared with the STX2 and STX3. It is balanced and weighted for hands-free operation, and the shallow electrode tips require less fluid than previous hand-held electrodes. With an adapter it may also be used with older versions of the EVOM and Millicell® meters. The STX4 electrode is the general-purpose electrode for the manually operated EVOM™ meters like the EVOM™ Manual and EVOM3. An EndOhm, together with the EVOM™ Manual, offers the most accurate, convenient and economical solution for trans membrane electrical resistance measurement.įor automation of TEER measurements, consider the REMS AutoSampler that integrates a robotic system and computer interface to automatically measure tissue resistance in 24- and 96-well plates.ĭownload the electrode comparison chart. With a fixed centered electrode geometry of the EndOhm, the variation of readings on the same sample is 1-2 Ω, as compared to 5% of the total reading using the STX2 electrodes. This figure demonstrates how the EVOM™ electrodes measures TEER. However, cell culture inserts need to be physically moved out of the plate to the EndOhm chamber for measurement. EndOhm electrodes by design are considered more accurate in capturing smaller changes.STX HTS electrodes are ideal for high throughput screening (HTS) plates. The STX4 electrode is our new and improved version of the STX2-PLUS electrode.
