  • 中文名稱：
    乙酰-組蛋白 H2B type 1-B (K20)重組抗體
  • 貨號：
    CSB-RA010402A20acHU
  • 規格：
    ￥1320
  • 圖片：
    • Western Blot
      Positive WB detected in Hela whole cell lysate treated by 15mM sodium butyrate for 30min
      All lanes Acetyl-Histone H2B type 1-B(K20)antibody at 0.135μg/ml
      Secondary
      Goat polyclonal to rabbit IgG at 1/50000 dilution
      Predicted band size: 15 KDa
      Observed band size: 15 KDa
    • Immunocytochemistry analysis of CSB-RA010402A20acHU diluted at 1:100 and staining in Hela cells performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4℃ overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
    • Immunofluorescence staining of Hela cells(treated by 15mM sodium butyrate for 30min) with CSB-RA010402A20acHU at 1:84,counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4℃.The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG (H+L).
    • Overlay histogram showing Hela cells stained with CSB-RA010402A20acHU (red line) at 1:50. The cells were fixed with 70% Ethylalcohol (18h) and then permeabilized with 0.3% Triton X-100 for 2 min.The cells were then incubated in 1x PBS /10% normal goat serum to block non-specific protein-protein interactions followed by primary antibody for 1 h at 4℃.The secondary antibody used was FITC goat anti-rabbit IgG (H+L) at 1/200 dilution for 1 h at 4℃. Control antibody (green line) was used under the same conditions. Acquisition of >10,000 events was performed.

靶點詳情

  • 功能：
    Core 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-translational modifications of histones, also called histone code, and nucleosome remodeling.
  • 基因功能參考文獻：

    2. RNF20 and H2Bub1 promotes chronic colonic inflammation and inflammation-associated colorectal cancer in mice and humans, partly by augmenting NF-kappaB activity and attenuating the antitumoral T cell response. PMID: 26854224
