ChIP: Chromatin prepared from HeLa cells. WB: HeLa, NIH/3T3 and PC12 nuclear lysate (triton enriched). Calf Thymus Histone Preparation Nuclear Lysate. ICC/IF: HeLa cells.
For detection of Histone H3 specifically methylated at position Lys 4. This antibody was used in a screen by Dover et al, (2002) to isolate yeast mutants that are unable to methylate Lysine 4. In immunofluorescence, this antibody detects foci in the nucleus that are non-colocalising with condensed chromatin. The perinuclear and perinucleolar heterochromatin are not stained with this antibody.

ChIP - Anti-Histone H3 (di methyl K4) antibody - ChIP Grade (ab7766)
Chromatin was prepared from HeLa cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 25µg of chromatin, 2µg of ab7766 (blue), and 20µl 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.
Peptide Array - Anti-Histone H3 (di methyl K4) antibody - ChIP Grade (ab7766)
All batches of ab7766 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 - di methyl K4 peptide (ab7768), indicating that this antibody specifically recognises the Histone H3 - di methyl K4 modification.

ab7766 staining Histone H3 (di methyl K4) in HeLa cells. The cells were fixed with 4% paraformaldehyde (10 min), permeabilized with 0.1% PBS-Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at 4°C with ab7766 at 5 µg/ml and ab7291, Mouse monoclonal [DM1A] to alpha Tubulin - Loading Control. Cells were then incubated with ab150081, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor® 488), pre-adsorbed at 1/1000 dilution (shown in green) and ab150120, Goat polyclonal Secondary Antibody to Mouse IgG - H&L (Alexa Fluor® 594), pre-adsorbed at 1/1000 dilution (shown in pseudocolour red). Nuclear DNA was labelled with DAPI (shown in blue).
Also suitable in cells fixed with 100% methanol (5 min).
Image was acquired with a high-content analyser (Operetta CLS, Perkin Elmer) and a maximum intensity projection of confocal sections is shown.

Western blot - Anti-Histone H3 (di methyl K4) antibody - ChIP Grade (ab7766)
MCF7 cells were incubated at 37°C for 24h with vehicle control (0 µM) and different concentrations of tranylcypromine hydrochloride (ab120606). Increased expression of Histone 3 K4 di-methyl (ab7766) in MCF7 cells correlates with an increase in tranylcypromine hydrochloride concentration, as described in literature.
Nuclear extracts were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 10 µg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 5% BSA before being incubated with ab7766 at 1 µg /ml and ab1791 at 1 µg /ml overnight at 4°C. Antibody binding was detected using an anti-rabbit HRP secondary antibody (ab97051) at 1/10000 dilution and visualized using ECL development solution.
