  • Validation Data


    Figure 1. ChIP results obtained with the Diagenode antibody directed against H4K8ac
    ChIP assays were performed using human HeLa cells, the Diagenode antibody directed against H4K8ac (cat. No. pAb-103- 050) and optimized PCR primer sets for qPCR. ChIP was performed with the “LowCell# ChIP” kit (cat. No. kch-maglow-016) on sheared chromatin from 10,000 cells using the SX-8G IP-Star automated system. A titration of the antibody consisting of 1, 2, 5, and 10 μg per ChIP experiment was analysed. IgG (1 μg/IP) was used as negative IP control. QPCR was performed with primers for the c-fos promoter and for the Sat2 satellite repeat region. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).


    Figure 2. Determination of the antibody titer
    To determine the titer of the antibody, an ELISA was performed using a serial dilution of the Diagenode antibody directed against H4K8ac (cat. No. pAb-103-050), crude serum and flow through 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 purified antibody was estimated to be 1:16,700.

    Dot Blot

    Figure 3. Cross reactivity test using the Diagenode antibody directed against H4K8ac
    A Dot Blot analysis was performed to test the cross reactivity of the Diagenode antibody against H4K8ac (cat. No. pAb-103-050) with peptides containing other histone modifications and the unmodified H4K8. 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.

    Western blot

    Figure 4. Western blot analysis using the Diagenode antibody directed against H4K8ac
    Histone extracts of HeLa cells (15 μg) were analysed by Western blot using the Diagenode antibody directed against H4K8ac (cat. No. pAb-103-050) diluted 1:200 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.


    Figure 5. Immunofluorescence using the Diagenode antibody directed against H4K8ac
    Mouse NIH3T3 cells were stained with the Diagenode antibody against H4K8ac (cat. No. pAb-103-050) 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 H4K8ac antibody (left) diluted 1:500 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.

  • Testimonials

    I have extensively used the antibodies against the histone modifications H3K4me3, H3k27me3, H3K9ac, H4k8ac and H3K18ac provided by Diagenode. The high level of specificity and selectivity of these antibodies in mouse brain samples, confirmed by using several negative and positive controls run in parallel with mouse brain tissue samples, ensured successful and reproducible results. I have been a Diagenode costumer for over one year now and I am extremely satisfied with the efficiency of the Bioruptor Pico for chromatin shearing as well as all of the ChIP materials (i.e., antibodies, blocking peptides, primer pairs for qPCR) provided by this company. Many thanks.

    Citrate modulates lipopolysaccharide-induced monocyte inflammatory responses.
    Ashbrook MJ, McDonough KL, Pituch JJ, Christopherson PL, Cornell TT, Selewski DT, Shanley TP, Blatt NB
    Citrate, a central component of cellular metabolism, is a widely used anti-coagulant due to its ability to chelate calcium. Adenosine triphosphate (ATP)-citrate lyase, which metabolizes citrate, has been shown to be essential for inflammation, but the ability of exogenous citrate to impact inflammatory signalling ca...

    Distribution of segmental duplications in the context of higher order chromatin organisation of human chromosome 7.
    Ebert G, Steininger A, Weißmann R, Boldt V, Lind-Thomsen A, Grune J, Badelt S, Heßler M, Peiser M, Hitzler M, Jensen LR, Müller I, Hu H, Arndt PF, Kuss AW, Tebel K, Ullmann R
    BACKGROUND: Segmental duplications (SDs) are not evenly distributed along chromosomes. The reasons for this biased susceptibility to SD insertion are poorly understood. Accumulation of SDs is associated with increased genomic instability, which can lead to structural variants and genomic disorders such as the Willia...

    Histone lysine trimethylation or acetylation can be modulated by phytoestrogen, estrogen or anti-HDAC in breast cancer cell lines.
    Dagdemir A, Durif J, Ngollo M, Bignon YJ, Bernard-Gallon D
    AIM: The isoflavones genistein, daidzein and equol (daidzein metabolite) have been reported to interact with epigenetic modifications, specifically hypermethylation of tumor suppressor genes. The objective of this study was to analyze and understand the mechanisms by which phytoestrogens act on chromatin in breast c...
