  • 阳性对照
    • WB: Calf thymus histone preparation and HeLa whole cell extract. IHC-P: Human normal skin tissue.
  • 常规说明

    Interphase: The cells within the culture show a considerable variability in the intensity of staining with the antibody. The relationship between trimethylation levels and cell cycle have not yet been determined but may be a contributor to the amount of methylation detected in each cell. Heterochromatic regions of the interphase nucleus are the primary sites of trimethylation observed by indirect immunofluroescence. Mitosis: Discrete chromosomal regions are labelled intensely, with lower level fluorescence throughout the remainder of the chromosome arms Data from IF performed by Kirk McManus in the lab of Michael Hendzel as part of the antibody characterisation at cellnucleus.com

应用

Our Abpromise guarantee covers the use of ab9051 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
IHC-P Use a concentration of 0.2 µg/ml.
IHC-Fr Use at an assay dependent concentration.
WB 1/1000. Can be blocked with Human Histone H4 (mono methyl K20) peptide (ab17043).
ICC/IF Use at an assay dependent concentration. Cautionary note: At low dilutions, the antibody may cross-react with microtubules. This can be minimized by increasing the dilution of the antibody when used in immunofluroescence.
Flow Cyt 1/200.

ab171870 - Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.

CHIPseq Use at an assay dependent concentration. PubMed: 22196736
ChIP Use 2-25 µg for 25 µg of chromatin.

    Performed under reducing conditions.

    Observed band size : 13 kDa (why is the actual band size different from the predicted?)


    Exposure time : 10 seconds
  • Chromatin was prepared from U2OS 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  ab9051 (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). Primers and probes are located in the first kb of the transcribed region.

  • IHC image of Histone H4 (mono methyl K20) staining in Human normal skin formalin fixed paraffin embedded tissue section*, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab9051, 0.2µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    Peptide competition (shown above lanes) at 1ug/ml.

    This peptide blocking study shows that ab9051 is specific for Histone H4 (mono methyl K20). The activity of the antibody is specifically blocked by the addition of the H4 mono methyl peptide (ab17043).
