  • Validation data


    Figure 1. ChIP results obtained with the Diagenode antibody directed against H3K4me3
    ChIP assays were performed using human U2OS cells, the Diagenode antibody against H3K4me3 (Cat. No. C15310003) and optimized PCR primer pairs for qPCR. ChIP was performed with the “OneDay ChIP” kit (Cat. No. C01010080), using sheared chromatin from 2 million cells and stringent washing conditions. A titration consisting of 1, 5 and 10 μl of antibody per ChIP experiment was analyzed. IgG (1 μg/ IP) was used as a negative IP control. Quantitative PCR was performed with primers for the promoter of the constitutively expressed GAPDH gene and for myoglobin exon 2. Figure 1 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 2. Determination of the antibody titer
    To determine the titer, an ELISA was performed using a serial dilution of the Diagenode antibody directed against human H3K4me3 (Cat. No. C15310003) in antigen coated wells. The antigen used was a peptide containing the histone modification of interest. By plotting the absorbance against the antibody dilution (Figure 2), the titer of the antibody was estimated to be 1:19,000.


    Figure 3. Cross reactivity tests 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. C15310003) with peptides containing other H3K4 methylations and the unmodified sequence. One hundred to 0.2 pmol of the respective peptides were spotted on a membrane. The antibody was used at a dilution of 1:20,000. Figure 3 shows a high specificity of the antibody for the modification of interest.


    Figure 4. Western blot analysis using the Diagenode antibody directed against H3K4me3
    Histone extracts of HeLa cells (15 μg) were analysed by Western blot using the Diagenode antibody against H3K4me3 (Cat. No. C15310003) diluted 1:1,000 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is indicated on the right; the marker (in kDa) is shown on the left.

    GRHL2-miR-200-ZEB1 maintains the epithelial status of ovarian cancer through transcriptional regulation and histone modification
    Chung VY, Tan TZ, Tan M, Wong MK, Kuay KT, Yang Z, Ye J, Muller J, Koh CM, Guccione E, Thiery JP, Huang RY
    Epithelial-mesenchymal transition (EMT), a biological process by which polarized epithelial cells convert into a mesenchymal phenotype, has been implicated to contribute to the molecular heterogeneity of epithelial ovarian cancer (EOC). Here we report that a transcription factor-Grainyhead-like 2 (GRHL2) maintains t...

    The complex pattern of epigenomic variation between natural yeast strains at single-nucleosome resolution.
    Filleton F, Chuffart F, Nagarajan M, Bottin-Duplus H, Yvert G
    BACKGROUND: Epigenomic studies on humans and model species have revealed substantial inter-individual variation in histone modification profiles. However, the pattern of this variation has not been precisely characterized, particularly regarding which genomic features are enriched for variability and whether dist...

    Caenorhabditis elegans chromatin-associated proteins SET-2 and ASH-2 are differentially required for histone H3 Lys 4 methylation in embryos and adult germ cells.
    Xiao Y, Bedet C, Robert VJ, Simonet T, Dunkelbarger S, Rakotomalala C, Soete G, Korswagen HC, Strome S, Palladino F
    Methylation of histone H3 lysine 4 (H3K4me), a mark associated with gene activation, is mediated by SET1 and the related mixed lineage leukemia (MLL) histone methyltransferases (HMTs) across species. Mammals contain seven H3K4 HMTs, Set1A, Set1B, and MLL1-MLL5. The activity of SET1 and MLL proteins relies on protein...
