  • Validation Data

    ELISA

    Figure 1. 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 H2A.XS139p (Cat. No. C15410219) 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 1), the titer of the antibody was estimated to be 1:170,000.

    Dot Blot

    Figure 2. Cross reactivity tests using the Diagenode antibody directed against H2A.XS139p
    To test the cross reactivity of the Diagenode antibody against H2A. XS139p (Cat. No. C15410219), a Dot Blot analysis was performed with peptides containing other histone phosphorylations and the unmodified H2A.X. One hundred to 0.2 pmol of the respective peptides were spotted on a membrane. The antibody was used at a dilution of 1:10,000. Figure 2 shows a high specificity of the antibody for the modification of interest.

    Western blot

    Figure 3. Western blot analysis using the Diagenode antibody directed against H2A.XS139p
    Western blot was performed on histone extracts (15 μg) from untreated U2OS cells (lane 1) or from U2OS cells treated with camptothecin (lane 2), and on 1 μg of recombinant histone H2A, H2B, H3 and H4 (lane 3, 4, 5 and 6, respectively) using the Diagenode antibody against H2A.XS139p (Cat. No. C15410219). The antibody was diluted 1:1,000 in TBS-Tween containing 5% skimmed milk. The marker (in kDa) is shown on the left.

    Immunofluorescence

    Figure 4. Immunofluorescence using the Diagenode antibody directed against H2A.XS139p
    U2OS cells, either treated with camptothecin (figure 4B) or untreated (figure 4A), were stained with the Diagenode antibody against H2A.XS139p (cat. No. C15410219) 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 H2A.XS139p 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.
