[Inductive-resonance energy transfer between chromophores localized in different parts of irradiated and nonirradiated erythrocyte ghosts].
A study was made of the inductive-resonance energy transfer between chromophore pairs, tryptophan--pyren, tryptophan--1.8-anilinonaphthalene sulfonate (ANS), puren--1.8-ANS, diphenylhexatrien--ethidium, and 1,8-ANS--ethidium, in irradiated (250 Gy) and nonirradiated preparations of erythrocytic membranes. The radiation--induced decrease in the energy transfer was noted in the pairs in which one of the chromophores was localized in a lipid phase. On the basis of the data obtained it is suggested that irradiation of membranes causes the lesions in them which lead to a reduction of the effective thickness of a hydrophobic part of the lipid bilayer.
