Award for Equipment Used to Assess Transepithelial/Transendothelial Electrical Resistance

In 2024, PETA Science Consortium International awarded free equipment to measure transepithelial/transendothelial electrical resistance (TEER). The EVOM Manual with the STX4 electrode by World Precision Instruments is the most recent and improved version of the equipment and is used to measure the voltage (potential difference) and TEER of epithelial or endothelial cell layers cultured on 12- and 24-well permeable membrane inserts.

Recipients of the EVOM Manual with the STX4 electrode

Professor Dr Jens Kurreck on behalf of Technische Universität Berlin, Institute of Biotechnology, Germany

“We are happy that we won this award. The TEER equipment is of key importance for the further development of our bioprinted lung models, which we use for infection studies. It will enable us to determine the tightness of the epithelial layer.” — Dr Kurreck

Sandra Czech, PhD student, Fraunhofer-Institut für Toxikologie und Experimentelle Medizin ITEM, Germany

“I’m delighted to be one of the winners! The use of the EVOM Manual for TEER Measurement with an STX4 electrode enable us to assess barrier functionality and proper differentiation of normal human bronchial epithelial (NHBE) cells exposed to typical lung toxicants.” — Sandra Czech

Recipient of the STX4 electrode

Dr Tom Ward, Senior Scientist, XCellR8 Ltd., UK

“XCellR8 are delighted to be a recipient of this award and would like to thank PETA Science Consortium International for selecting our work! We are excited to put the STX4 electrode to use in our new inhalation toxicity project.” — Dr Ward
