H1 Histone Protein (IMAGE)
Caption
Here are three views of the same human cells with different staining of the nucleus. In the frame on the left, the cells are stained with an antibody attached to a green fluorescent tag that targets a single phosphorylation site on the H1 histone protein. The center panel shows that in the same cells Bromo‑UTP preferentially labels sites of ribosomal RNA synthesis. On the right, both types of fluorescence show that the phosphorylated HI histone is found at high levels in regions of RNA synthesis.
