一般描述
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. Dimethylation of histone H3 at Lys4 correlates with transcriptional activity of many genes.

Anti-dimethyl Histone H3 (Lys4) Antibody is a Rabbit Polyclonal Antibody for detection of Histone H3 dimethylated at lysine 4. This purified polyclonal antibody, also known as H3K4me2, has dot blot (DB) proven specificity & has been validated in WB, ICC, ChIP.
Immunocytochemistry Analysis:
1:500 dilution from a representative lot detected Histone H3 in NIH/3T3 and A431 cells.
Dot Blot Analysis:
1:1,000 dilution from a representative lot specifically detected Histone H3 in a Lys4 dimethhyl modified histone H3 peptide while not detecting potential cross-reacting peptides corresponding to other modified and non-modified histones.
Chromatin Immunoprecipitation Analysis:
Sonicated chromatin prepared from HeLa cells (1 X 10E6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using 4 ?g of either Normal IgG (Part No. 12-370), or 4 ?L of Anti-Dimethyl Histone H3 (Lys4) (Part No. ABE250) and the Magna ChIP
