Intro for TEER Assay Article From Cellqart

How often do you or your colleagues perform TEER (Transepithelial-Transendothelial Electrical Resistance) assays in a given week, and how confident are you in your results?

The accuracy of your TEER assay measurements depends on four things:

• Temperature - It’s recommended you perform yours at exactly 37°C.
• Electrode positioning - The lower chamber electrode must touch the bottom of the well and the upper chamber electrode must not touch the membrane.
• Vibrations - Vibrations can alter electrode placement and they cause disturbance of the electric field across the monolayer

The 4th factor is membrane quality, and there’s now a cell culture insert membrane that undergoes 100% in-line quality control of every segment, making it a revolutionary upgrade to your lab’s TEER assay workflow.

Decide for yourself if it’s right for you and your colleagues.
