General description

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.


Broad species cross-reactivity expected due to sequence homology.
Recognizes Histone H3, Mr 17 kDa


KLH-conjugated, synthetic peptide corresponding to the C-terminus of human Histone H3.


Chromatin Immunoprecipitation:
2 μL of this antibody immunoprecipitated chromatin associated with Histone H3 from a wild type yeast lysate.
Use Anti-Histone H3 Antibody, CT, pan, clone A3S (Rabbit Monoclonal Antibody) validated in ChIP, WB to detect Histone H3 also known as Histone H3.


Routinely evaluated by western blot analysis.

Western Blot Analysis:
1:2,000-1:20,000 dilution of this lot detected Histone H3 in a modification independent manner in acid extracted proteins from untreated, sodium butyrate or colcemid treated HeLa cells.

Target description

17 kDa

Physical form

Format: Purified
Purified rabbit monoclonal IgG in buffer containing 0.014 M phosphate buffer, pH 7.6, 0.175 M NaCl, 0.07% sodium azide and 30% glycerol.

Storage and Stability

Stable for 1 year at -20ºC from date of receipt.

Handling Recommendations:
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol-containing solutions to become frozen during storage.

Analysis Note

Acid extracted proteins from HeLa cells, HeLa nuclear extracts or acid extracted HeLa cells treated with sodium butyrate.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.

Cancer development involves changes driven by the epigenetic machinery, including nucleosome positioning. Recently, the concept that adenoviral replication may be driven by tumor specific promoters (TSPs) gained support, and several conditionally replicative adenoviruses (CRAd) exhibited therapeutic efficacy in clinical trials.
