Immunocytochemistry/ Immunofluorescence - Anti-Histone H2B antibody - ChIP Grade (AB1790)

ICC/IF image of ab1790 stained HeLa cells. The cells were 100% methanol fixed (5 min) then permeabilised using 0.1% PBS-Triton and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to further permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab1790 at 0.1μg/ml overnight at +4°C. The secondary antibody (pseudo-colored green) was Alexa Fluor® 488 goat anti- rabbit (ab150081) IgG (H+L) preadsorbed, used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1h at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43μM for 1hour at room temperature.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Histone H2B antibody - ChIP Grade (AB1790)

IHC image of Histone H2B staining in human breast carcinoma FFPE section, performed on a Bond^TM 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 ab1790, 1µg/ml, for 8 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.

Immunoprecipitation - Anti-Histone H2B antibody - ChIP Grade (AB1790)

Histone H2B - ChIP Grade was immunoprecipitated using 0.5mg HeLa whole cell extract, 5μg of Rabbit polyclonal to and 50μl of protein G magnetic beads (+). No antibody was added to the control (-).

The antibody was incubated under agitation with Protein G beads for 10min, HeLa whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.

Proteins were eluted by addition of 40μl SDS loading buffer and incubated for 10min at 70°C; 10μl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab1790.

Secondary : Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).

ChIP - Anti-Histone H2B antibody - ChIP Grade (AB1790)

Chromatin was prepared from U2OS cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10min. The ChIP was performed with 25μg of chromatin, 2μg of ab1790 (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.

ChIP - Anti-Histone H2B antibody - ChIP Grade (AB1790)

Chromatin from Xenopus laevis oocytes was prepared according to the Abcam X-ChIP protocol. Oocytes were fixed with formaldehyde for 10 min. The ChIP was performed with 25 μg of chromatin, 3 μg of ab1790 (anti-H2B, light blue) and 3 μg of ab1791 (anti-H3, dark blue), and 20 μl of Protein A/G sepharose beads. A non-specific antibody was used as a control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach).

Western blot - Anti-Histone H2B antibody - ChIP Grade (AB1790)

ab1790 at 1/3000 detecting Histone H2B from Xenopus laevis (S phase egg extracts - whole cell lysates 60ug per lane) by Western Blot. The egg extracts were fractionated using a gel filtration column and every other fraction (4 - 26) was loaded onto a 8-16% gel. The input corresponds to 1ul of crude extract. In this experiment an HRP conjugated donkey anti-rabbit antibody was used as the secondary.
