Ussing chamber

An Ussing chamber is an experimental device used to study the transport properties of biological membranes, particularly epithelia. It allows researchers to measure the movement of ions, nutrients, and other molecules across a membrane in a controlled environment. The chamber is named after the Danish physiologist Paul Ussing, who developed the technique in the 1950s. The Ussing chamber consists of two half-chambers separated by a membrane (usually a piece of intestinal tissue).
