HeLa cells were methanol fixed for 10 minutes and then blocked with 1% BSA containing PBS. The fixation step stabilizes the morphology of the cells and permeabilizes membranes. (A) Cells were labeled with the H3K4me3 Polyclonal Antibody, Rabbit (diluted 1:200 and incubated for 1 hour at room temperature) followed by a FITC-labeled goat anti-rabbit secondary antibody. (B) Nuclei were stained using the DNA-specific stain DAPI. Both, the H3K4me3 Polyclonal Antibody, Rabbit and DAPI produced clear nuclear staining.

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.
