  ChIP - Anti-Histone H3 (tri methyl K27) antibody [mAbcam 6002] - ChIP Grade (ab6002)

  Chromatin was prepared from K562 cells. Cells were fixed with formaldehyde for 10 min. A GATA1 antibody was used as the positive control and a Rabbit IgG was used as the negative control. Incubation with primary antibody was in Immuno Precipitation Dilution buffer for 16 hours at 4°C. The immunoprecipitated DNA was quantified by real time PCR.

  Western blot - Anti-Histone H3 (tri methyl K27) antibody [mAbcam 6002] - ChIP Grade (ab6002)

  This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 3% milk before being incubated with ab6002 overnight at 4°C. Antibody binding was detected using an anti-mouse antibody conjugated to HRP, and visualised using ECL development solution ECL Substrate Kit (High Sensitivity) ab133406.

  IHC - Wholemount - Anti-Histone H3 (tri methyl K27) antibody [mAbcam 6002] - ChIP Grade (ab6002)

  In mice, the X-inactivation process is reversed naturally by X-reactivation in blastocysts and germ cells and in culture in pluripotent stem cells. The image shows late blastocyst-stage mouse embryos consisting of three cell types: epiblast (NANOG-positive, cyan), primitive endoderm (GATA4-positive, red) and trophectoderm (CDX2-positive, green). The inactive X-chromosome (H3K27me3-positive, yellow dots) is reactivated only in the epiblast (cells without yellow spots), which will form the embryo. The germ cell factor PRDM14 and the long noncoding RNA Tsix collaborate during the X-reactivation process in blastocysts and pluripotent stem cells and thereby link epigenetic with cellular reprogramming events.

  ELISA - Anti-Histone H3 (tri methyl K27) antibody [mAbcam 6002] - ChIP Grade (ab6002)

  All batches of ab6002 are tested in ELISA against peptides to different Histone H3 modifications. Results show strong binding to Histone H3 - tri methyl K27 peptide (Human Histone H3 (tri methyl K27) peptide ab1782), indicating that this antibody specifically recognizes the Histone H3 tri methyl K27 modification. Weak binding is also detected against the Histone H3 di methyl K27 modification (<12%) (Human Histone H3 (di methyl K27) peptide ab1781).

  This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin (lanes 1-3) and 3% milk (lanes 4-6) before being incubated with ab6002 overnight at 4°C. Antibody binding was detected using an anti-mouse antibody conjugated to HRP, and visualised using ECL development solution ECL Substrate Kit (High Sensitivity) ab133406.

  Immunocytochemistry/ Immunofluorescence - Anti-Histone H3 (tri methyl K27) antibody [mAbcam 6002] - ChIP Grade (ab6002)

  ICC/IF image of ab6002 stained HeLa cells. The cells were 4% PFA fixed (10 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 (ab6002, 5μg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-mouse IgG (H+L) used at a 1/1000 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. This antibody also gave a positive result in 4% PFA fixed (10 min) Hek293, HepG2 and MCF7 cells at 5μg/ml, and in 100% methanol fixed (5 min) HeLa, Hek293, HepG2 and MCF7 cells at 5μg/ml.

  ChIP - Anti-Histone H3 (tri methyl K27) antibody [mAbcam 6002] - ChIP Grade (ab6002)

  Chromatin was prepared from Hela cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10min. The ChIP was performed with 25μg of chromatin, 5μg of ab6002 (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.
