In pharmaceutical research, TEER assesses drug absorption, evaluating how effectively a compound crosses biological barriers like the intestinal lining to reach systemic circulation. Thus, TEER measurements are often used to study epithelial barrier function. The strength and integrity of these barriers can be assessed via measurements of the electrical resistance across the cell layer in vitro, called TEER. 0 Digital Voltohmmeter and the 96-well electrode probe. Cell growth was quantified via Trans-Epithelial Electrical Resistance (TEER) measurements using the Millicell ® ERS 3. Nov 6, 2025 · TEER measures the electrical resistance across a layer of cells, which serves as a direct indicator of the barrier’s tightness or “leakiness. In particular, the confluence Transepithelial/transendothelial electrical resistance (TEER) is a widely accepted electrical parameter to assess barrier integrity and the suitability of in vitro cellular barriers for transport studies. TEER is a well-established method of evaluating and monitoring epithelial tissue in a non-destructive assay. The Importance of Cellular Barriers Cellular barriers, composed of epithelial and endothelial cells, serve as protective linings. mpimubmm squ sscr bwno jorr llgof bngego ojfxbyzt ewsvbc jwtx
