In this study, we performed proteomic profiling of a nuclear fraction of Jurkat T lymphocyte cells under radiation along different time course by means of 2DE and MALDI TOF-MS. We found 24 protein spots whose expression had changed after radiation, including relevant proteins, genetic material proteins, metabolism proteins, molecular chaperon and nuclear membrane proteins. Based on the above it is concluded that the combination of fluorescence labeled 2D-PAGE and MALDI-TOF MS is more precisely and effectively to elucidate the protein changes in Jurkat T lymphocyte cells after irradiation.展开更多
