Target

  • RelevanceCore component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post- modifications of histones, also called histone code, and nucleosome remodeling. P68431 and Q71DI3 are expressed during S phase, then expression strongly decreases as cell division slows down during the process of differentiation. Q16695 is expressed in tesicular cells. Q6NXT2 is specifically expressed in the seminiferous tubules of testis and this Hominid-specific H3.5/H3F3C preferentially colocalizes with euchromatin, and it is associated with actively transcribed genes. P84243 is a variant histone H3 which replaces conventional H3 in a wide range of nucleosomes in active genes. Constitutes the predominant form of histone H3 in non-dividing cells and is incorporated into chromatin independently of DNA synthesis. Deposited at sites of nucleosomal displacement throughout transcribed genes, suggesting that it represents an epigenetic imprint of transcriptionally active chromatin. Post-translational modification. Citrullination at Arg-9 (H3R8ci) and/or Arg-18 (H3R17ci) by PADI4 impairs methylation and represses transcription.

Anti-Histone H3 (citrulline R2 + R8 + R17) antibody - ChIP Grade images

  • All batches of ab5103 are tested in Peptide Array against peptides to different Histone H3 modifications. Six dilutions of each peptide are printed on to the Peptide Array in triplicate and results are averaged before being plotted on to a graph. Results show strong binding to Histone H3 - citrulline 2 + 8 + 17 peptide (ab32876), indicating that this antibody specifically recognises the Histone H3 - citrulline 2 + 8 + 17 modifications.

    Secondary antibody - goat anti-rabbit HRP (ab97051)

  • Chromatin immunoprecipitation using ab5103 on the pS2 promoter. Times are after stimulation by estrogen (Ul).
  • ICC/IF image of ab5103 stained human HeLa cells. The cells were PFA fixed (10 min), permabilised in TBS-T (20 min) and incubated with the antibody (ab5103, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).
  • ab5103 staining Histone H3 (citrulline 2 + 8 + 17) in Mouse bone marrow cells by Immunocytochemistry/ Immunoflourescence. Cells were fixed in formaldehyde and permeabilized in 0.1% Triton X-100 prior to blocking in 5% Goat serum for 2 hours at 25°C. The primary antibody was diluted 1/250 in PBS and incubated with the sample for 12 hours at 4°C. The secondary antibody was Alexa Fluor® 488-conjugated Goat anti-Rabbit polyclonal, diluted 1/500.
    Nuclei were counterstained blue with DAPI.
