靶标

  • 功能
    Variant histone H2A which replaces conventional H2A in a subset of nucleosomes. 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-translational modifications of histones, also called histone code, and nucleosome remodeling. May be involved in the formation of constitutive heterochromatin. May be required for chromosome segregation during cell division.
  • 序列相似性
    Belongs to the histone H2A family.
  • 翻译后修饰
    Monoubiquitination of Lys-122 gives a specific tag for epigenetic transcriptional repression.
    Acetylated on Lys-5, Lys-8 and Lys-12 during interphase. Acetylation disappears at mitosis.
    Monomethylated on Lys-5 and Lys-8 by SETD6. SETD6 predominantly methylates Lys-8, lys-5 being a possible secondary site.
    Not phosphorylated.

Anti-Histone H2A.Z antibody - ChIP Grade 图像

  • Chromatin was prepared from Hela cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 min. The  ChIP was performed with 25 µg of chromatin, 2 µg of  ab4174 (blue), and 20 µl of Protein A/G sepharose beads. No antibody was added to the beads control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach for active and inactive loci, Sybr green approach for heterochromatic loci). Primers and probes are located in the first kb of the transcribed region.



  • Performed under reducing conditions.

    Predicted band size : 13.4 kDa
  • The staining has been done on mouse embryonic cells. The fixation is 2% PFA, and permeabilization is PBS 0.5% triton BSA. The dilution used was 1 in 100 (but it could be used at 1/200 to1/300)

    Red  = H2A.Z
    Blue  = toto3 for the DNA


  • Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 13.4 kDa


    Exposure time : 3 minutes

  • This image was kindly supplied as part of the review submitted by Dr Geza Fejes-Toth.
  • ICC/IF image of ab4174 stained HepG2 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab4174, 5µg/ml) overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti-rabbit IgG - H&L, pre-adsorbed (ab96899) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
