Takeo Kamino et al.
A technique for high resolution transmission electron microscopic (TEM) observation of nano-materials at very high temperatures has been developed. A spirally wound tungsten wire, normally used as the heating element of a high resolution-hi...
Comparative structural biology of the genome: nano-scale imaging of single nucleus from different kingdoms reveals the common physicochemical property of chromatin with a 40 nm structural unit [0.03%]
基因组结构生物学的比较研究：来自不同界别的单个细胞核的纳米成像显示染色质具有一个共同的物理化学性质，并以40nm为结构单位
Toshiro Kobori,Mami Kodama,Kohji Hizume et al.
Toshiro Kobori et al.
Genome function is closely linked to the higher-order chromatin structures. To reveal a structural basis for the interphase chromatin organization, the 'on-substrate' lysis procedure was applied to nuclei isolated from human HeLa cells, chi...
