Epithelial cells are polarized and have tight junctions that contribute to barrier function. Assessment of barrier function typically involves measurement of electrophysiological parameters or movement of nonionic particles across an epithelium. Here, we describe measurement of transepithelial electrical conductance or resistance, determination of dilution potential, and assessment of flux of nonionic particles such as dextran or mannitol, with particular emphasis on Ussing chamber techniques.
