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 25 µg of chromatin, 5 µg of ab32388 (red), and 20 µl of Protein A/G sepharose beads. No antibody was added to the beads control (gray). The immunoprecipitated DNA was quantified by real time PCR (Sybr green approach).
Primers and probes are located in the first kb of the transcribed region.
Immunofluorescent analysis of 4% Paraformaldehyde-fixed, 0.1% tritonX-100 permeabilized HeLa (Human epithelial cell line from cervix adenocarcinoma) cells, LP starved and non-starved, labeling anti-Histone H3 (phospho S28) with Ab32388 at 1/100 dilution followed by Goat anti-Rabbit secondary IgG AlexaFluor®488 (ab150077) secondary antibody at 1/1000 dilution (green).
Confocal image showing nuclear staining on M phase of HeLa cells, then the signal decreased after LP treatment.
For the pan antibody, there was no great difference after LP treatment. The data showed mostly nuclear staining
Blocking/dilution buffer: 2% BSA/TBST
Dot blot performed using ab32388 at a dilution of 1/100. Lane 1 - Unmodified H3 peptide. Lane 2 - H3S28ph peptide. Lane 3 - H3.3S28ph peptide. Lane 4 - H3.3S31ph peptide. A HRP conjugated goat anti-rabbit (H+L) was used as the secondary antibody at a dilution of 1/2500. The exposure time was 3 minutes and the dilution and blocking buffer used were 5% NFDM/TBST.
IHC image of ab32388 staining Histone H3 in Human normal 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 ab32388, 0.1ug/ml, 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.
