  ChIP - Anti-Histone H4 (acetyl K5) antibody [EP1000Y] - ChIP Grade (ab51997)

  Chromatin was prepared from MEF (Mouse embryonic fibroblast cell line) cells according to the Abcam X-ChIP protocol. Cells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 25μg of chromatin, 5μg of ab51997 (red), and 20 μl protein A/G sepharose beads. 2μg of rabbit normal IgG was added to the beads control (grey). The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).

  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Histone H4 (acetyl K5) antibody [EP1000Y] - ChIP Grade (ab51997)

  IHC image of unpurified ab51997 staining Histone H4 (acetyl K5) in human colon formalin fixed paraffin embedded tissue sections, performed on a Leica Bond. 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 ab51997, 1/200 dilution, 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. No primary antibody was used in the negative control (shown on the inset).
  

  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.

  ICC/IF image of unpurtified ab51997 stained HeLa cells. The cells were 100% methanol fixed (5 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 (ab51997, 1/1000 dilution) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit 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.

  ChIP - Anti-Histone H4 (acetyl K5) antibody [EP1000Y] - ChIP Grade (ab51997)

  Chromatin was prepared from MCF7 breast cancer cell lysate. 5 ug total antibody was preincubated overnight on Protein A- Dynabeads and the chromatin (2X 15 cm dishes - around 15-20 million MCF7 cells) was incubated overnight with antibody-coupled beads. Beads were washed 6 times with modified RIPA buffer (50mM HEPES pH 7.6, 1mM EDTA, 0.7% Na deoxycholate, 1% NP-40, 0.5M LiCL) and one time with TE. DNA was eluted with TE containing 1% SDS, treated with RNAseA and Proteinase K, phenol-chloroform extracted and then made libraries for Illumina sequencing.
