The term originates from Latin and means "out of the living''; it refers to an experiment that is done in or on living tissue, and at least partially outside the organism. For example, for the measurement of ex vivo receptor binding, an animal can be treated with a test compound in vivo, followed by removal of the brain, exposure of brain slices with a radioligand specific for that binding site in vitro, and subsequent quantification of the amount of radioactivity in brain areas of interest. The degree to which radioactivity is reduced due to competitive binding of the test substance can be taken as a measure of receptor occupancy.
