Applications

  • STX-100 Electrodes are designed for TEER measurement in HTS culture plates using the EVOM2™

Semi-permeable HTS (high throughput screening) culture plates have become a standard tool for pharmaceutical and institutional research in epithelial transport. HTS culture plates have well cups which are bonded together into a single assembly and are not removable. This makes the plates ideal for automated applications, but imposes a significant inconvenience when TEER must be measured in the absence of an automated system. WPI’s STX100 series electrodes provide a cost-effective alternative to automation, allowing HTS well plates to be measured manually using a hand–held electrode.

The spatial orientation of an electrode during TEER measurement can have a significant effect on the resistance reading. When compared to the STX-2 “chopsticks” electrode, the STX100 series electrodes offer a technical advantage. The design of the STX100 series electrodes guarantees spatial repeatability. Each STX100 electrode is designed to self-align based on the form factor of the apical and basal access ports of the HTS plate. Each manufacturer of HTS culture systems has a unique form factor, and the correct STX100 electrode to use is manufacturer specific.

WPI developed STX100 electrodes for 24 and 96 well plates specific to Corning, BD Falcon and Millipore. Refer to the charts for compatibility information or contact your WPI sales representative for assistance. If an automated system is preferable for your application, investigate WPI’s automated TEER measurement system (REMS).
