Abstract Trans-epithelial Electrical Resistance (TEER) can be used as a measure of cell monolayer confluence, health, and integrity. An Epithelial Voltohmmeter (EVOM) is used to take TEER measurements. This method details how to take TEER readings using an EVOM with chopstick electrode.Please note that chopstick electrodes are only designed for use with 12 mm inserts.Disclaimer: The contents of this article have been reviewed by the US Environmental Protection Agency and approved for publication and do not necessarily represent Agency policy.

Abstract This protocol is intended for culture of primary human tracheobronchial epithelial cells (pHBEC) obtained by brush biopsy during clinical bronchoscopy, or purchased commercially, using Lonza-based medium.Note: This is a historical protocol. At the time of publication, this protocol has been superseded by a different version in the McCullough lab; however, it is being published to support the transparency and reproducibility of other studies by which it is referenced.Disclaimer: The information presented here has been reviewed and approved for publication by the US Environmental Protection Agency do not necessarily represent Agency policy.

Abstract Trans-epithelial Electrical Resistance (TEER) can be used as a measure of cell monolayer confluence, health, and integrity. An EndOhm chamber connected to an Epithelial Voltohmmeter (EVOM) may be used to take TEER measurements that are more reproducible than the chopsticks electrode. This method details how to take TEER readings using an EndOhm-12 chamber and EVOM2 resistance reader. Read the manufacturer’s manual carefully before adjusting any of the parameters below as the conditions described here were determined to meet the manufacturer’s specifications. Volumes will need to be adjusted to accommodate substitution of the EndOhm-6 or EndOhm-24.Disclaimer: The contents of this article have been reviewed by the US Environmental Protection Agency and approved for publication and do not necessarily represent Agency policy.
