    H4K20me1 Antibody ChIP Grade

    Figure 1. ChIP results obtained with the Diagenode monoclonal antibody directed against H4K20me1
    ChIP assays were performed using human HeLa cells, the Diagenode monclonal antibody against H4K20me1 (cat. No. C15200147) and optimized PCR primer sets for qPCR. ChIP was performed with the “the “iDeal ChIP-seq” kit (cat. No. C01010051), using sheared chromatin from 1 million cells. A titration of the antibody consisting of 0.5, 1, 2 and 5 μg per ChIP experiment was analysed. IgG (1 μg/IP) was used as negative IP control. QPCR was performed with primers for the coding region of the active GAPDH and ACTB genes, used as positive controls, and for the GAPDH promoter and a region located 1 kb upstream of the GAPDH promoter, 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 monoclonal antibody directed against H4K20me1
    ChIP was performed as described above using 0.5 μg of the Diagenode antibody against H4K20me1 (cat. No. C15200147). The IP’d DNA was subsequently analysed on an Illumina HiSeq. Library preparation, cluster generation and sequencing were performed according to the manufacturer’s instructions. The 51 bp tags were aligned to the human genome using the BWA algorithm. Figure 2 shows the peak distribution in genomic regions from chromosomes 12, 7, 14 and 3 surrounding the GAPDH, ACTB, FOS and EIF4A2 positive control genes (figure 2A, B, C and D, respectively).

    H4K20me1 Antibody Dot Blot validation

    Figure 3. Cross reactivity tests using the Diagenode monoclonal antibody directed against H4K20me1
    To check the specificity of the Diagenode monoclonal antibody against H4K20me1 (cat. No C15200147) a Dot Blot was performed with peptides containing different modifications of histone H3 and H4 or the unmodified H4K20 sequence. One hundred to 0.2 pmol of peptide containing the respective histone modification were spotted on a membrane. The antibody was used at a dilution of 1:20,000. Figure 3 shows a high specificity of the antibody for the modification of interest.

    Figure 4. Western blot analysis using the Diagenode monoclonal antibody directed against H4K20me1
    Western blot was performed on whole cell (25 μg, lane 1) and histone extracts (15 μg, lane 2) from HeLa cells, and on 1 μg of recombinant histone H2A, H2B, H3 and H4 (lane 3, 4, 5 and 6, respectively) using the Diagenode monoclonal antibody against H4K20me1 (cat. No C15200147). The antibody was diluted 1:1,000 in TBS-Tween containing 5% skimmed milk. The marker (in kDa) is shown on the left, the position of the protein is indicated on the right

    Figure 5. Immunofluorescence using the Diagenode monoclonal antibody directed against H4K20me1
    Human osteosarcoma (U2OS) cells were stained with the Diagenode antibody against H4K20me1 (cat. No. MAb-147- 100) and with DAPI. Cells were fixed with ice cold methanol for 10’ and blocked with PBS/TX-100 containing 5% normal goat serum. Figure 4A: cells were immunofluorescently labeled with the H4K20me1 antibody (left), diluted 1:200 in blocking solution followed by an anti- mouse antibody conjugated to Alexa488 or with DAPI (right), which specifically labels DNA.

  • Target Description

    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.

    Inhibition of the SET8 Pathway Ameliorates Lung Fibrosis Even ThroughFibroblast Dedifferentiation
    Ugai, Keita and Matsuda, Shuichi and Mikami, Hideki and Shimada, Ayako andMisawa, Tomoko and Nakamura, Hiroyuki and Tatsumi, Koichiro and Hatano,Masahiko and Murayama, Toshihiko and Kasuya, Yoshitoshi
    Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease of unknown etiopathogenesis. The activation of extracellular matrix (ECM)-producing myofibroblasts plays a key role in fibrotic tissue remodeling. The dedifferentiation of myofibroblasts has attracted considerable attention as a promising target for the dev...

    SETBP1 induces transcription of a network of development genes by acting as an epigenetic hub.
    Piazza R, Magistroni V, Redaelli S, Mauri M, Massimino L, Sessa A, Peronaci M, Lalowski M, Soliymani R, Mezzatesta C, Pirola A, Banfi F, Rubio A, Rea D, Stagno F, Usala E, Martino B, Campiotti L, Merli M, Passamonti F, Onida F, Morotti A, Pavesi F, Bregni
    SETBP1 variants occur as somatic mutations in several hematological malignancies such as atypical chronic myeloid leukemia and as de novo germline mutations in the Schinzel-Giedion syndrome. Here we show that SETBP1 binds to gDNA in AT-rich promoter regions, causing activation of gene expression through recruitment ...

    SET8 methyltransferase activity during the DNA double-strand break response is required for recruitment of 53BP1
    Dulev, S., Tkach, J., Lin, S. and Batada, N. N.
    DNA double-strand breaks (DSBs) activate a signaling pathway known as the DNA damage response (DDR) which via protein–protein interactions and post-translational modifications recruit signaling proteins, such as 53BP1, to chromatin flanking the lesion. Depletion of the SET8 methyltransferase prevents accumulation of...
