  • Validation Data


    Figure 1. ChIP results obtained with the Diagenode antibody directed against H3K9me3S10p
    ChIP assays were performed using human HeLa cells treated with colcemid, the Diagenode antibody against H3K9me3S10p (cat. No. CS-128-100) and optimized PCR primer sets for qPCR. ChIP was performed with the “LowCell# ChIP” kit (cat. No. kch-maglow-016), using sheared chromatin from 10,000 cells per IP. A titration of the antibody consisting of 1, 5, and 10 μl per ChIP experiment was analysed. Additionally, the same titration was analysed after incubation of the antibody with 5 nmol blocking peptide (cat. No. sp-128-050) for 1 hour at room temperature. IgG (5 μg/IP) was used as negative IP control. QPCR was performed with primers for the promoter of the active genes GAPDH (cat. No. pp-1001-050) and c-fos (cat. No. pp- 1004-050) and for the heterochromatin marker Sat2 (cat. No. pp-1040-050). 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 titer
    To determine the titer, an ELISA was performed using a serial dilution of the Diagenode antibody directed against human H3K9me3S10p (cat. No. CS-128-100). 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 1:87,000.

    Dot Blot

    Figure 3. Cross reactivity test using the Diagenode antibody directed against H3K9me3S10p
    A Dot Blot analysis was performed to test the cross reactivity of the Diagenode antibody against H3K9me3S10p (cat. No. CS-128-100) with peptides containing other modifications and unmodified sequences of histone H3. One hundred to 0.2 pmol of the peptide containing the respective histone modification were spotted on a membrane. The antibody was used at a dilution of 1:1,000. 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 H3K9me3S10p
    HeLa cells were treated with colcemid to block the cell cycle in metaphase and 15 μg of histone extracts of these cells were analysed by Western blot with the Diagenode antibody against H3K9me3S10p (cat. No. CS-128-100) diluted 1:500 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. The result of the Western analysis with the antibody is shown in lane 2; lane 1 shows the same analysis after incubation of the antibody with 5 nmol blocking peptide (cat. No. sp-128-050) for 1 hour at room temperature.


    Figure 5. Immunofluorescence using the Diagenode antibody directed against H3K9me3S10p
    HeLa cells were stained with the Diagenode antibody against H3K9me3S10p (cat. No. CS-128-100) 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 H3K9me3S10p 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.

    BACKGROUND: An adverse intrauterine environment leads to permanent physiological changes including vascular tone regulation, potentially influencing the risk for adult vascular diseases. We therefore aimed to monitor responsive NOS3 expression in human umbilical artery endothelial cells (HUAEC) and to study the unde...
