Improved User Experience
EVOM™ Auto is the latest generation of WPI’s automated transepithelial or transendothelial electrical resistance (TEER) measurement system. Using the same proven technology in the EVOM™ Manual and REMS, combined with a new multi-electrode array, software interface and control system, it delivers our fastest workflow solution while improving TEER measurement accuracy: - Faster throughput – read a 96-well plate in under 3.5 minutes (A 2-rinse cycle can be completed in 7 minutes, almost halving the time compared to a REMS)
- Automatic sample averaging improves accuracy and stability
- Compact size for easy set up and operation inside in a hood or incubator
- Wireless control of the autosampler
- Smart user interface and web...more

April 13, 2023World Precision Instruments (WPI) is excited to launch the newest member to its EVOM™ family of products, the EVOM™ Auto. The new EVOM™ Auto enables rapid and reproducible measurements of Transepithelial Electrical Resistance (TEER), a well-established and widely accepted method of evaluating epithelial and endothelial cells and tissues, in vitro. WPI’s EVOM™ Auto combines TEER technology with high throughput screening capabilities, resulting in the automated measurement of resistance in 96-well cell culture plates. This data gives scientists and drug discovery laboratories insights into tissue and monolayer barrier integrity, cell permeability, cell confluency, and can readout the critical physiology of barrier tissues such as the blood-brain barrier, the gastrointestinal tract, the lung, and the skin. ...more

Optimized, in vitro workflow to identify compounds with vasoactive properties
In vitro models have employed two common methods to quantify changes in endothelial barrier integrity: transepithelial/transendothelial electrical resistance (TEER) and tracer compound permeability.1 TEER is a non-invasive method that quantifies changes in electrical conductance to measure confluency and barrier integrity. Tracer compound permeability uses molecules of defined molecular weights to measure the size exclusion capacity of cell barriers (e.g., 4 kDa FITC-dextran or FD4).1 Using the EVOM™ Manual (EVOM-MT-03-01) with the EndOhm TEER electrode and cell culture permeable supports, this application note describes how to non-invasively evaluate endothelial barrier integrity after cytokine treatment and provides a method to identify vasoactive compounds that have the potential to induce vascular injury. Tracer compound permeability studies...more
