一般描述
Histones are highly conserved proteins that serve as the structural scaffold for the organization of nuclear DNA into chromatin. The four core histones, H2A, H2B, H3, and H4, assemble into an octamer (2 molecules of each). Subsequently, 146 base pairs of DNA are wrapped around the octamer, forming a nucleosome, the basic subunit of chromatin. Histones are modified post-translationally by the actions of enzymes in both the nucleus and cytoplasm. These modifications regulate DNA transcription, repair, recombination, and replication. The most commonly studied modifications are acetylation, phosphorylation, methylation, and ubiquitination. These modifications occur predominantly on the N-terminal and C-terminal tails that extend beyond the nucleosome core particle. Di- and trimethylation of histone H3 at Lys4 correlates with transcriptional activity of many genes. Dimethylation of Histone H3 at Lys4 occurs at both active and inactive euchromatic regions but not in silent heterochromatic sites, whereas trimethylation at Lys4 is present exclusively at active genes.
特异性
Histone H3 dimethylated on lysine 4
The immunizing sequence is conserved from Tetrahymena to human, so broad species cross-reactivity is expected.
免疫原
KLH-conjugated, synthetic peptide containing the sequence …Tme2KQT… in which me2K corresponds to dimethyl-lysine at residue 4 of human histone H3.
应用
Anti-dimethyl-Histone H3 (Lys4) Antibody, clone AW30 is a rabbit monoclonal antibody for detection of dimethyl-Histone H3 (Lys4) also known as H3K4me2, Histone H3 (di methyl K4) & has been validated in WB, ChIP, ChIP-seq, DB, PIA, Mplex.

Western Blot Analysis:
A 1:1000-1:2000 dilution of this lot detected dimethyl histone H3 (Lys4) in HeLa acid extracts.
Western Blot Analysis:
A 1:2,000 to 1:10,000 dilution of a previous lot detected methylated histone H3 in acid extracted proteins from HeLa cells. The antibody did not detect unmethylated recombinant Histone H3.
ChIP-seq Analysis:
Representative lot data. Chromatin immunoprecipitation was performed using the Magna ChIP
Dot Blot Analysis:
Absurance Histone H3 Antibody Specificity Array (Cat. No. 16-667) and Absurance Histone H2A, H2B, H4 Antibody Specificity Array (Cat. No. 16-665), which contain histone peptides with various modifications were probed with Cat. No 04-790, Anti-dimethyl Histone H3 (Lys4), clone AW30 at 1:1000 dilution. Proteins were visualized using a Donkey anti-Rabbit IgG conjugated to HRP and a chemiluminescence detection system.
Peptide Inhibition Analysis:
2 μM of a histone H3 peptide containing dimethyl-lysine 4 abolished detection of histone H3 by a previous lot of antibody in immunoblot analysis of HeLa acid extracts. No signal reduction was observed with histone H3 peptides containing either monomethyl or trimethyl-lysine 4 modifications
质量
routinely evaluated by immunoblot on acid-extracted proteins from HeLa cells; the antibody did not detect unmethylated recombinant Histone H3 (Catalog #14-494)
