ABSTRACT White light induces delayed luminescence in mammalian cells at normal body temperature. A high sensitivity photon counting method makes it possible to achieve accuracy in the low range of a few photons per second and that allows the characterization of this delayed luminescence. Recent results concerning delayed luminescence by cultured hepatoma cells are reviewed and interesting examples are given to demonstrate the pitfalls in the application of quantitative photon counting methods for studying weak delayed luminescence of animal origin.
