    Figure 1. ChIP results obtained with the Diagenode antibody directed against H3K4me3
    ChIP assays were performed using human HeLa cells, the Diagenode antibody against H3K4me3 (Cat. No. C15410030) and optimized PCR primer pairs for qPCR. ChIP was performed with the “iDeal ChIP-seq” kit (cat. No. C01010051), using sheared chromatin from 1 million cells. The chromatin was spiked with a panel of in vitro assembled nucleosomes, each containing a specific lysine methylation (SNAP-ChIP K-MetStat Panel, Epicypher). A titration consisting of 1, 2, 5 and 10 µg of antibody per ChIP experiment was analyzed. IgG (2 µg/IP) was used as a negative IP control. Figure 1A. Quantitative PCR was performed with primers specific for the promoter of the active GAPDH and EIF4A2 genes, used as positive controls, and for the inactive MYOD1 gene, used as negative control. The graph shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis). These results are in accordance with the observation that trimethylation of K4 at histone H3 is associated with the promoters of active genes Figure 1B. Recovery of the nucleosomes carrying the H3K4me1, H3K4me2, H3K4me3 modifications and the unmodified H3K4 as determined by qPCR. The figure clearly shows the antibody is very specific in ChIP for the H3K4me3 modification. At higher concentrations some H3K4me2 is also precipitated.

    D. H3K4me3 Antibody validated in ChIP-seq

    Figure 2. ChIP-seq results obtained with the Diagenode antibody directed against H3K4me3
    ChIP was performed on sheared chromatin from 1 million HeLa cells using 1 µg of the Diagenode antibody against H3K4me3 (Cat. No. C15410030) as described above. The IP'd DNA was subsequently analysed on an Illumina Genome Analyzer. Library preparation, cluster generation and sequencing were performed according to the manufacturer's instructions. The 50 bp tags were aligned to the human genome using the BWA algorithm. Figure 2 shows the peak distribution along the complete sequence and a 1.2 Mb region of the X-chromosome (figure 2A and B) and in two regions surrounding the GAPDH and EIF4A2 positive control genes, respectively (figure 2C and D). These results clearly show an enrichment of the H3K4 trimethylation at the promoters of active genes.

    H3K4me3 Antibody validated in Dot Blot

    Figure 3. Cross reactivity test using the Diagenode antibody directed against H3K4me3
    A Dot Blot analysis was performed to test the cross reactivity of the Diagenode antibody against H3K4me3 (Cat. No. C15410030) with peptides containing other modifications and unmodified sequences of histone H3 and H4. One hundred to 0.2 pmol of the respective peptides were spotted on a membrane. The antibody was used at a dilution of 1:2,000. Figure 3 shows a high specificity of the antibody for the modification of interest.

    H3K4me3 Antibody validated in Western Blot

    Figure 4. Western blot analysis using the Diagenode antibody directed against H3K4me3
    Western blot was performed on whole cell (40 µg, lane 1) and histone extracts (15 µg, lane 2) from HeLa cells, and on 1 µg of recombinant histone H2A, H2B, H3.1, H3.3 and H4 (lane 3, 4, 5, 6 and 7, respectively) using the Diagenode antibody against H3K4me3 (Cat. No. C15410030). The antibody was diluted 1:500 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is shown on the right, the marker (in kDa) is shown on the left.

    H3K4me3 Antibody validated in Immunofluorescence

    Figure 5. Immunofluorescence using the Diagenode antibody directed against H3K4me3
    HeLa cells were stained with the Diagenode antibody against H3K4me3 (Cat. No. C15410030) and with DAPI. Cells were fixed with 4% formaldehyde for 10’ and blocked with PBS/TX-100 containing 5% normal goat serum and 1% BSA. The cells were immunofluorescently labelled with the H3K4me3 antibody (left) diluted 1:100 in blocking solution followed by an anti-rabbit antibody conjugated to Alexa488. The middle panel shows staining of the nuclei with DAPI. A merge of the two stainings is shown on the right.

  • Target Description

    Histones are the main constituents of the protein part of chromosomes of eukaryotic cells. They are rich in the amino acids arginine and lysine and have been greatly conserved during evolution. Histones pack the DNA into tight masses of chromatin. Two core histones of each class H2A, H2B, H3 and H4 assemble and are wrapped by 146 base pairs of DNA to form one octameric nucleosome. Histone tails undergo numerous post-translational modifications, which either directly or indirectly alter chromatin structure to facilitate transcriptional activation or repression or other nuclear processes. In addition to the genetic code, combinations of the different histone modifications reveal the so-called “histone code”. Histone methylation and demethylation is dynamically regulated by respectively histone methyl transferases and histone demethylases. Trimethylation of histone H3K4 is associated with active promoters.

    Butz S. et al.
    Genomic imprinting is regulated by parental-specific DNA methylation of imprinting control regions (ICRs). Despite an identical DNA sequence, ICRs can exist in two distinct epigenetic states that are memorized throughout unlimited cell divisions and reset during germline formation. Here, we systematically study the ...

    Altered Chromatin States Drive Cryptic Transcription in AgingMammalian Stem Cells.
    McCauley Brenna S et al.
    A repressive chromatin state featuring trimethylated lysine 36 on histone H3 (H3K36me3) and DNA methylation suppresses cryptic transcription in embryonic stem cells. Cryptic transcription is elevated with age in yeast and nematodes, and reducing it extends yeast lifespan, though whether this occurs in mammals is unk...

    Bellegarde F, Maghiaoui A, Boucherez J, Krouk G, Lejay L, Bach L, Gojon A, Martin A
    Reactive oxygen species (ROS) can accumulate in cells at excessive levels, leading to unbalanced redox states and to potential oxidative stress, which can have damaging effects on the molecular components of plant cells. Several environmental conditions have been described as causing an elevation of ROS production i...

    Polycomb Repressive Complex 2 attenuates the very high expression of the Arabidopsis gene NRT2.1.
    Bellegarde F, Herbert L, Séré D, Caillieux E, Boucherez J, Fizames C, Roudier F, Gojon A, Martin A
    PRC2 is a major regulator of gene expression in eukaryotes. It catalyzes the repressive chromatin mark H3K27me3, which leads to very low expression of target genes. NRT2.1, which encodes a key root nitrate transporter in Arabidopsis, is targeted by H3K27me3, but the function of PRC2 on NRT2.1 remains unclear. Here, ...

    Veselovska L, Smallwood SA, Saadeh H, Stewart KR, Krueger F, Maupetit-Méhouas S, Arnaud P, Tomizawa S, Andrews S, Kelsey G
    BACKGROUND: Previously, a role was demonstrated for transcription in the acquisition of DNA methylation at imprinted control regions in oocytes. Definition of the oocyte DNA methylome by whole genome approaches revealed that the majority of methylated CpG islands are intragenic and gene bodies are hypermethylated...

    Phalke S, Mzoughi S, Bezzi M, Jennifer N, Mok WC, Low DH, Thike AA, Kuznetsov VA, Tan PH, Voorhoeve PM, Guccione E
    p21 is a potent cyclin-dependent kinase inhibitor that plays a role in promoting G1 cell cycle arrest and cellular senescence.

    Transcription and histone methylation changes correlate with imprint acquisition in male germ cells.
    Henckel A, Chebli K, Kota SK, Arnaud P, Feil R
    Genomic imprinting in mammals is controlled by DNA methylation imprints that are acquired in the gametes, at essential sequence elements called 'imprinting control regions' (ICRs). What signals paternal imprint acquisition in male germ cells remains unknown. To address this question, we explored histone methylation ...
