Here are some Frequently Asked Questions (FAQ) regarding Transepithelial Electrical Resistance (TEER) measurement.
The EVOM2 is the classic, hand-held instrument for making Trans Epithelial Electrical Resistance (TEER) measurements. The REMS system adds a robot and data recording for automated TEER measurements. There may be times when you don't have a robot, but would still like to have the data recording capabilities of the REMS system. With a little ingenuity, you can do just that. Here, we will show you how you can add data recording to your standard EVOM2.
The REMS AutoSampler automates measurements of electrical resistance of transepithelial, transendothelial or Caco-2 cell membranes being grown to confluence on microporous filters of high throughput screening (HTS) 24- and 96-well microplates.
This video gives a quick overview of the brand new REMS system for TEER measurement.
If the resistance reading from your Endohm don't stabilize, you may need to do some troubleshooting.
WPI's STX100 electrodes for Trans-epithelial electrical resistance (TEER) measurements increase accuracy and reproducibility of TEER readings (±5) of the STX100 electrode compared to the standard STX2.
WPI offers the EVOM2 meter with a variety of electrodes for manual TEER measurement. Your your High Throughput Screening (HTS) needs, WPI offers the REMS system, which includes a robotic arm. For more flexibility, you may use the REMS-KIT electrode that can be mounted in your own robotic system.
