Chromatin

These images contrast the appearance of chromatin at the electron microscopic level. Euchromatin appears electron lucent (left panel) because it is dispersed and, therefore, binds less metal. In contrast, highly condensed chromatin binds metals at high density, which produces a darker image, as seen in the right panel. Mucus-secreting cells (L) 5000x; Fibroblast (R) 7000x
