Understanding TEER: The Gold Standard for Barrier Integrity Research
Cell barriers protect our most vital organs, from the blood-brain barrier safeguarding neural tissue to intestinal epithelium controlling what enters our bloodstream. But how do researchers measure when these critical barriers are compromised?
Answer: TEER (Transepithelial Electrical Resistance) is a powerful, non-invasive technique that's revolutionizing how we study barrier function.

Why TEER matters:
• Quantitative & reproducible measurements
• Real-time monitoring without cell damage
• Applications from drug development to disease modeling
• Essential for studying neurological diseases, gut health, and organ function

Whether you're investigating Alzheimer's disease effects on the blood-brain barrier or developing treatments for inflammatory bowel conditions, TEER provides the precise data needed to advance therapeutic discoveries.
For researchers ready to dive deeper into barrier function studies, mastering TEER opens doors to groundbreaking research possibilities.
