PRESS RELEASE: EVOM Auto with Both 24 & 96 Capability
SARASOTA, Fla., October 23, 2023 /PRNewswire/ -- World Precision Instruments (WPI) is excited to expand the capability of the EVOM™ Auto, now offering both 24 and 96 multiwell capacity in one single platform. The EVOM™ Auto enables rapid and reproducible measurements of Transepithelial Electrical Resistance (TEER), a well-established, non-invasive and widely accepted method of evaluating epithelial and endothelial cells and tissues.
How to Troubleshoot TEER Measurement Problems
Transepithelial/transendothelial electrical resistance (TEER) measurement is one of the most used practices to evaluate cellular health, such as cellular confluence, barrier integrity, or barrier function of cellular monolayers grown onto multiwells. The TEER measurement using WPI’s Epithelial Voltohmmeter (EVOM) is considered the gold standard because of its reliable measurements and numerous literature citations using various cell types. The EVOM™ Manual and EVOM™ Auto along with different choices of electrodes (STX4, STX HTS high throughput screening, EndOhm chambers, and multielectrode array for EVOM™ Auto) allow researchers to perform and analyze cell samples in 6, 12, and 24 removable inserts and 24 and 96 HTS multiwell plate formats. The major challenges researchers may encounter while performing studies to capture TEER measurement include:
· Unstable read outs
· Out of range values
· Inconsistent measurements among sample replicates or batches.
Consider the following factors to overcome any TEER measurement problems and obtain accurate and reliable measurements.
What are the Benefits of TEER?
Transepithelial Electrical Resistance (TEER) is a widely used technique in the life sciences fields and therapeutic development. It measures the electrical resistance across a cell monolayer, providing information about the integrity and functionality of epithelial barriers. TEER has proven to be a valuable tool in various fields, including drug absorption studies, tissue engineering, and disease modeling. This article aims to explore the benefits of TEER and its applications in different research areas.
