  • Validation Data


    Figure 1. ChIP results obtained with the Diagenode antibody directed against HP1α, ß and γ
    ChIP assays were performed using NIH3T3 cells and 4 μg of the Diagenode antibody directed against HP1α, ß and γ (Cat. No. C15410071). QPCR was performed on the IP’d DNA with optimized primer sets for the rDNA promoter and for a subtelomeric sequence of chromosome 19. Figure 1 shows the relative enrichment as compared to a no antibody negative control ChIP.

    Western blot

    Figure 2. Western blot analysis using the Diagenode antibody directed against HP1α, ß and γ
    Western blot was performed on nuclear extracts from HeLa cells (20 μg) with the Diagenode antibody against human HP1α, ß and γ (Cat. No. C15410071) diluted 1:1,000 in TBS-Tween containing 5% skimmed milk (Figure 1). The molecular weight marker (in kDa) is shown on the left; the expected location of HP1α, HP1ß and HP1γ is indicated on the right.


    Figure 3. Immunofluorescence using the Diagenode antibody directed against HP1α, ß and γ
    HeLa cells were stained with the Diagenode antibody against HP1α, ß and γ (Cat. No. C15410071) 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 HP1α, ß and γ 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.

    Spatiotemporal control of estrogen-responsive transcription in ERα-positive breast cancer cells.

    Recruitment of transcription machinery to target promoters for aberrant gene expression has been well studied, but underlying control directed by distant-acting enhancers remains unclear in cancer development. Our previous study demonstrated that distant estrogen response elements (DEREs) located on chromosome 20q13...
