    ChIP using anti-H3K18me2 | Histone H3 (dimethyl Lys18) polyclonal antibodies
    Chromatin Immunoprecipitation using anti-H3K18me2 antibodies. Chromatin from one million formaldehyde cross-linked Hela cells was used with 2 μg of H3K18me2 antibody and 20 μl of magnetic IgG beads per immunoprecipitation. A no antibody (No Ab) control was also used. Immunoprecipitated DNA was quantified using real-time PCR and normalized to the input chromatin.

    dot blot using anti-H3K18me2 | Histone H3 (dimethyl Lys18) polyclonal antibodies
    Dot Blot using anti-H3K18me2 antibodies. Lane 1: K18 unmodified. Lane 2: K18Me2. Lane 3: K18Me3. Lane 4: K18ac. Lane 5: K18Me1. Load: 0.1, 0.3, and 1 picomoles of peptide. Primary antibody used at a 1:1 000 dilution for 45 min at 4°C. Secondary antibody: Dylight®488 rabbit secondary antibody at 1:10 000 for 45 min at RT.

    Immunofluorescence using anti-H3K18me2 | Histone H3 (dimethyl Lys18) polyclonal antibodies
    Immunofluorescence using anti-H3K18me2 antibodies. Tissue: HeLa cells. Fixation: 0.5% PFA. Primary antibody used at a 1:500 dilution for 1 h at RT. Secondary antibody: Dylight® 488 secondary antibody at 1:10 000 for 45 min at RT. Localization: Histone H3K18me2 is nuclear and chromosomal. Staining: Histone H3K18me2 is expressed in green, nuclei and alpha-tubulin are counterstained with DAPI (blue) and Dylight® 594 (red).

    western blot using anti-H3K18me2 | Histone H3 (dimethyl Lys18) polyclonal antibodies
    Western Blot using anti-H3K18me2 antibodies. 30 μg of NIH-3T3 histone extract. Primary antibody used at a 1:500 dilution overnight at 4°C. Secondary antibody: IRDye800™ rabbit secondary antibody at 1:10 000 for 45 min at RT.

  • Background
  • Background: The di-methylated K18 on histone H3 is a seemingly transient post-translational modification. H3K18 is better known to be acetylated, and occasionally mono-methylated. Suv39h1, a well-studied histone methyltransferase seems to be responsible for the transition of acetylation and methylation at this H3 modification site. The di-methylated K18 on H3 seems to be associated with embryological development and possibly implantation.
