WebOct 6, 2016 · The total CFTR Cl−conductance of the apical membrane is dependent on three parameters: the activity, or open state probability (Po) of CFTR, which is controlled predominantly via cAMP/PKA phosphorylation as described in chapter “Biochemistry and physiology of CFTR”; the number or density of CFTR channels (N), and finally the single … 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. TEER has proven to be a highly sensitive and reliable method to …
