  • Validation Data

    ChIP

    Figure 1. ChIP results obtained with the Diagenode antibody directed against BRD4
    ChIP was performed with the Diagenode antibody against BRD4 (Cat. No. C15410337) on sheared chromatin from 4,000,000 K562 cells. An antibody titration consisting of 1, 2, 5 and 10 µg per ChIP experiment was analysed. IgG (2 µg/IP) was used as negative IP control. QPCR was performed with primers specific for the EIF4A2 and ACTB promoters, used as positive controls, and for the MYOD1 gene and Sat2 satellite repeat, used as negative controls. 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. ChIP-seq results obtained with the Diagenode antibody directed against BRD4
    ChIP was performed with 2 µg of the Diagenode antibody against BRD4 (cat. No. C15410337) on sheared chromatin from 4,000,000 K562 cells using the “iDeal ChIP-seq” kit as described above. The IP'd DNA was subsequently analysed on an Illumina HiSeq 2000. Library preparation, cluster generation and sequencing were performed according to the manufacturer's instructions. The 50 bp tags were aligned to the human genome using the BWA algorithm. Figure 2 shows the signal distribution along the complete sequence and a 300 kb region of the human X-chromosome (figures 2A and B), and in two genomic rtegions surrounding the ACTB and EIF4A2 positive control genes (figure 2C and D).

    ELISA

    Figure 3. 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 BRD4 (Cat. No. C15410337). The plates were coated with the peptides used for immunization of the rabbit. By plotting the absorbance against the antibody dilution (Figure 2), the titer of the antibody was estimated to be 1:290,000.

    Figure 4. Western blot analysis using the Diagenode antibody directed against BRD4
    Whole cell extracts (25 µg) from HeLa cells were analysed by Western blot using the Diagenode antibody against BRD4 (Cat. No. C15410337) 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.

    DeltaNp63-dependent super enhancers define molecular identity in pancreatic cancer by an interconnected transcription factor network.
    Hamdan FH, Johnsen SA
    Molecular subtyping of cancer offers tremendous promise for the optimization of a precision oncology approach to anticancer therapy. Recent advances in pancreatic cancer research uncovered various molecular subtypes with tumors expressing a squamous/basal-like gene expression signature displaying a worse prognosis. ...
