    H2A.Zac Antibody for ChIP

    Figure 1. ChIP results obtained with the Diagenode antibody directed against H2A.Zac
    Figure 1A ChIP assays were performed using human HeLa cells, the Diagenode antibody against H2A.Zac (Cat. No. C15410202) and optimized PCR primer pairs for qPCR. ChIP was performed with the ““Auto Histone ChIP-seq” kit (Cat. No. AB-Auto02-A100) on the IP-Star automated system, using sheared chromatin from 1,000,000 cells. A titration consisting of 1, 2, 5 and 10 μg of antibody per ChIP experiment was analyzed. IgG (2 μg/IP) was used as a negative IP control. Figure 1B ChIP assays were performed using human K562 cells, the Diagenode antibody against H2A.Zac (Cat. No. C15410202) and optimized PCR primer sets for qPCR. ChIP was performed with the “iDeal ChIP-seq” kit (Cat. No. AB-001-0024) on sheared chromatin from 100,000 cells. A titration of the antibody consisting of 0.2, 0.5, 1 and 2 μg per ChIP experiment was analysed. IgG (1 μg/IP) was used as negative IP control. Quantitative PCR was performed with primers specific for the promoter of the active genes CCT5 and EIF4A2, used as positive controls, and for the coding region of the inactive MYT1 gene and the 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 H2A.Zac
    ChIP was performed on sheared chromatin from 100,000 K562 cells using 1 μg the Diagenode antibody against H2A.Zac (Cat. No. C15410202) with the “iDeal ChIP-seq” kit (Cat. No. AB-001-0024) as described above. The IP’d DNA was subsequently analysed with an Illumina Genome Analyzer. Library preparation, cluster generation and sequencing were performed according to the manufacturer’s instructions. The 36 bp tags were aligned to the human genome using the ELAND algorithm. Figure 2 shows the peak distribution along the complete sequence and a 1.5 Mb region of the X-chromosome (figure 2A and B) and in two regions surrounding the EIF4A2 and CCT5 positive control genes, respectively (figure 2C and D).

    H2A.Zac Antibody ELISA validation

    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 against H2A.Zac (Cat. No. C15410202). The antigen used was a peptide containing the histone modifications of interest. By plotting the absorbance against the antibody dilution (Figure 3), the titer of the antibody was estimated to be 1:56,600.

    H2A.Zac Antibody validated in  Dot Blot

    Figure 4. Cross reactivity tests using the Diagenode antibody directed against H2A.Zac
    To test the cross reactivity of the Diagenode antibody against H2A.Zac (Cat. No. C15410202), a Dot Blot analysis was performed with peptides containing different multiple acetylations and the unmodified H2A.Z. One hundred to 0.2 pmol of the respective peptides were spotted on a membrane. The antibody was used at a dilution of 1:20,000. Figure 4 shows a high specificity of the antibody for the modification of interest.

    H2A.Zac Antibody validated in Western Blot

    Figure 5. Western blot analysis using the Diagenode antibody directed against H2A.Zac
    Western blot was performed on whole cell extracts (25 μg, lane 1) from HeLa cells, and on 1 μg of recombinant histone H2A, H2B, H3 and H4 (lane 2, 3, 4 and 5, respectively) using the Diagenode antibody against H2A.Zac (Cat. No. C15410202). The antibody was 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.

    H2A.Zac Antibody validated in Immunofluorescence

    Figure 6. Immunofluorescence using the Diagenode antibody directed against H2A.Zac
    HeLa cells were stained with the Diagenode antibody against H2A.Zac (Cat. No. C15410202) 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 labeled with the H2A.Zac 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

    Histones are the main constituents of the protein part of chromosomes of eukaryotic cells. They are rich in the amino acids arginine and lysine and have been greatly conserved during evolution. Histones pack the DNA into tight masses of chromatin. Two core histones of each class H2A, H2B, H3 and H4 assemble and are wrapped by 146 base pairs of DNA to form one octameric nucleosome. Histone tails undergo numerous post-translational modifications, which either directly or indirectly alter chromatin structure to facilitate transcriptional activation or repression or other nuclear processes. In addition to the genetic code, combinations of the different histone modifications reveal the so-called “histone code”. Histone methylation and demethylation is dynamically regulated by respectively histone methyl transferases and histone demethylases. Acetylation of the histone H2A variant H2A.Z is associated with the promoters of active genes.

    Schwann cells ensure efficient nerve impulse conduction in the peripheral nervous system. Their development is accompanied by defined chromatin changes, including variant histone deposition and redistribution. To study the importance of variant histones for Schwann cell development, we altered their genomic distribu...

    PWWP2A binds distinct chromatin moieties and interacts with an MTA1-specific core NuRD complex.

    Chromatin structure and function is regulated by reader proteins recognizing histone modifications and/or histone variants. We recently identified that PWWP2A tightly binds to H2A.Z-containing nucleosomes and is involved in mitotic progression and cranial-facial development. Here, using in vitro assays, we show that...
