  • Validation Data

    ChIP

    Figure 1. ChIP results obtained with the Diagenode antibody directed against H3K79me2
    ChIP assays were performed using human osteosarcoma (U2OS) cells, the Diagenode antibody against H3K79me2 (cat. No. CS-051-100) and optimized PCR primer sets for qPCR. Chromatin was sheared with the Diagenode “Shearing ChIP” kit (cat. No. kch-redmod-100). ChIP was performed with the “OneDay ChIP” kit (cat. No. kch-oneDIP-060), using sheared chromatin from 1.6 million cells. A titration of the antibody consisting of 2, 7 and 15 μl per ChIP experiment was analysed. Additionally, ChIP was performed with 2 and 15 μl of antibody after incubation with 5 nmol blocking peptide for 1 hour at room temperature. IgG (5 μg/IP) was used as negative IP control. QPCR was performed with primers for the ALDOA (fructose-bisphosphate aldolase A) promoter and for the coding region of the myogenic differentiation gene (MYOD), a gene that is inactive at normal conditions. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).

    ELISA

    Figure 2. Determination of the titer
    To determine the titer, an ELISA was performed using a serial dilution of the Diagenode antibody directed against H3K79me2 (cat. No. CS-051-100). 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 1:4,500.

    Dot Blot

    Figure 3. Cross reactivity test using the Diagenode antibody directed against H3K79me2
    A Dot Blot analysis was performed to test the cross reactivity of the Diagenode antibody against H3K79me2 (cat. No. CS-051-100) with peptides containing other modifications of histone H3. Other H3 modifications include mono- and trimethylation of the same lysine and mono-, di- and trimethylation of lysine 9, 27 and 36. 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 1:50,000. 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 H3K79me2
    Histone extracts of HeLa cells (15 μg) were analysed by Western blot using the Diagenode antibody against H3K79me2 (cat. No. CS-051-100) diluted 1:250 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is indicated on the left; the marker (in kDa) is shown on the right.
