Histone H3 is one of the five main histone proteins involved in the structure of chromatin in eukaryotic cells.
Featuring a main globular domain and a long N-terminal tail, H3 is involved with the structure of the nucleosomes of the 'beads on a string' structure.
The N-terminal tail of histone H3 protrudes from the globular nucleosome core and can undergo several different types of epigenetic modifications 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.
Applications:Suitable for use in Immunofluorescence, Western Blot and Immunocytochemistry.
Other applications not tested.
Recommended Dilution:Western Blot: 1:5000-1:10,000 detects phosphorylated Histone H3 in acid extracted proteins from mitotic HeLa cells but not unphosphorylated recombinant Histone H3.
Recombinant Histone H3 protein and acid extract from colcemid-treated HeLa cells were resolved by electrophoresis, transferred to nitrocellulose and probed with a 1:5,000 dilution of antiphospho-Histone H3 (Thr3).
Proteins were visualized using a goat anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system
Optimal dilutions to be determined by the researcher.
Positive Control:Acid extract from colcemid-treated HeLa cells
