Asynchronous HeLa cells were formaldehyde fixed, permeabilized with sodium citrate and Triton® X-100 (Dow Chemical Co) and blocked with PBS containing 2.5% BSA. (A) Cells were labeled with the anti-H3K27me3S28p crude serum (diluted 1:200 and incubated for 1 hour at room temperature) followed by labeled goat anti-rabbit secondary antibody (Fisher Scientific). (B) Nuclei were stained using the DNA-specific stain DAPI. Phosphorylation of H3 on serine 28 is increased during late G2 phase and reaches a maximum in metaphase cells. This may explain the different staining intensities of different cells.

Histone H3 is one of the DNA-binding proteins found in the chromatin of all eukaryotic cells. H3 along with four core histone proteins binds to DNA forming the structure of the nucleosome. Histones play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. Post tranlationally, histones are modified in a variety of ways to either directly change the chromatin structure or allow for the binding of specific transcription factors. The N-terminal tail of histone H3 protrudes from the globular nucleosome core and can undergo several different types of post-translational modification that influence cellular processes. These modifications include the covalent attachment of methyl or acetyl groups to lysine and arginine amino acids and the phosphorylation of serine or threonine.
