[Study of the structural changes in irradiated erythrocyte membranes using 2,6-toluidinonaphthalene sulfonate]

It was shown that 2,6-tolyidinonaphthalene sulfonate (2,6-TNS) is localized mainly at the bilayer-water border of the erythrocytic membranes. Under the effect of gamma-radiation the rearrangements occur in the membrane which bring about changes in the distribution of the probe between the membrane and the medium. The lifetime of the excited state of 2,6-TNS after irradiation varies slightly.
