title: Effect of air ions on L 1210 cells: changes in fluorescence of membrane-bound 1,8-aniline-naphthalene-sulfonate (ANS) after in vitro exposure of cells to air ions.
abstract: The ability of air ions to produce changes in the electrical properties of L 1210 mouse leukemia cells was tested. The fluorescence of ANS incorporated into a membrane lipid bilayer (measured microphotometrically) was used as a probe. It was shown that the action of air ions of both signs could change (negative ions by increasing and the positive ones by decreasing) the fluorescence intensity of ANS in the cell surface structures or to an imbalance of ions inside and outside the cell. Both possibilities are discussed in the light of the results of experiments using ouabain or biguanide as factors diminishing the intensity of ANS fluorescence.
