Transepithelial/Endothelial Electrical Resistance (TEER) qualitatively measures cellular monolayer health and quantitatively evaluates cellular confluence by measuring the electrical resistance across a cell monolayer. It is commonly used to assess the integrity and permeability of cellular barriers, such as epithelial and endothelial cell layers in cell culture plates. Organ-on-Chip platforms are an emerging market for TEER applications. Let’s look at what TEER is and how it is used.

Transepithelial/Transendothelial Electrical Resistance (TEER) is a widely used quantitative technique to assess the integrity of tight junctions in cell monolayers. WPI’s EVOM™ is the gold standard for TEER measurement and is particularly valuable in studies involving drug transport, toxicology, inflammation, and organ-on-chip systems. TEER measurement provides fast and quantitative data and can be used as an efficient and cost-effective method for drug discovery and development. There are certain biological and technical factors that are known to affect TEER readings. This article reviews the key variables that influence TEER outcomes in cell culture studies and how to ensure consistent TEER measurement analysis can be done by minimizing or eliminating the effects of these factors.

Cell barriers, such as the intestinal epithelium, blood–brain barrier, or corneal endothelium, are critical for controlling what enters and exits tissues. A compromised barrier can lead to disease, while a strong barrier is essential for maintaining health.
Understanding how our body's protective barriers function is crucial for advancing treatments and developing new therapies. For researchers, accurately measuring barrier integrity is vital in fields ranging from drug development to disease modeling. One of the most important tools scientists use to study these barriers is TEER (Transepithelial Electrical Resistance or Transendothelial Electrical Resistance). This powerful measurement technique provides valuable insights into the integrity and function of cellular barriers that protect our organs and tissues. TEER is a gold-standard, non-invasive technique for quantifying the integrity and permeability of cell monolayers grown in culture.
