Study of the aggregation of membrane proteins of erythrocyte ghosts using SDS-PAAG electrophoresis

Using the method of electrophoresis in SDS-PAAG the authors showed a diminution of proteins of bands I + II (spectrins) and III (major integral protein) after irradiation of erythrocyte ghosts with doses of 50 to 1000 Gy. We failed to ascertain that radiation-induced lipid peroxidation is involved into membrane protein aggregation. Among the radiolysis products, OH-radicals were shown to contribute markedly to the radiation effect observed.
