  Immunocytochemistry/ Immunofluorescence - PE Anti-Histone H3 (di methyl K4) antibody [Y47] (ab208741)

  ab208741 staining Histone H3 (di methyl K4) in HeLa cells. The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% 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 ab208741 at 1/500 dilution (Pseudocolored in green) and Alexa Fluor® 647 Anti-Tubulin antibody [YOL1/34] - Microtubule Marker ab195884, Rat monoclonal to Tubulin (Alexa Fluor^® 647), at 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).
  

  Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

  This product also gave a positive signal under the same testing conditions in HeLa cells fixed with 100% methanol (5min).

  Flow Cytometry (Intracellular) - PE Anti-Histone H3 (di methyl K4) antibody [Y47] (ab208741)

  Overlay histogram showing HeLa cells stained with ab208741 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilized with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab208741, 1/500 dilution) for 30 min at 22°C.
  

  Isotype control antibody (black line) was rabbit IgG monoclonal [EPR25A] (PE Rabbit IgG, monoclonal [EPR25A] - Isotype Control ab209478) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

  Acquisition of >5,000 events were collected using a 20 mW Solid State Blue Laser (488nm) and 585/40 bandpass filter.

  This antibody gave a positive signal in HeLa cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Triton X-100 for 15 min used under the same conditions.
