Chromatin

Chromatin is a complex of protein and DNA.  The staining characteristic of chromatin indicates the level of transcriptional activity in the cell.  These light micrographs contrast euchromatin, which is pale-staining and transcriptionally active, with heteochromatin, which is dark staining and transcriptionally less active.  Neuron (L)  1000x; Thymus (R)  400x
