Transepithelial / transendothelial electrical resistance (TEER) is an electrophysiological technique widely adopted for use in Organ-on-a-chip systems. It uses Ohmic contact resistance to serve as a proxy for the permeability of a cellular monolayer. TEER therefore enables researchers to miniaturize assays such as Caco-2 permeability, Blood–brain barrier transfer, or membrane integrity assays in Microfluidic systems.
