Results showed that the chromatin in the interphase nucleus of chicken erythrocyte was not in a disorganized form but represented a higher_order conformation. The thin sections of the chromatin in the nucleus of chicken erythrocyte were examined with a transmission electron microscope (TEM). Compared with TEM, AFM had the advantages that the samples did not need the preparation procedures such as fixing, sectioning and staining, and thus were closer to their native condition.展开更多
