Synthetic peptide of Human Histone H3, tri methylated at K9.
Our Abpromise guarantee covers the use of ab71604 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|Flow Cyt||Use 1µg for 106 cells.|
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 17 kDa (predicted molecular weight: 15 kDa).Can be blocked with Human Histone H3 (tri methyl K9) peptide (ab1773).|
|ICC/IF||Use a concentration of 1 - 5 µg/ml.|
|IHC-P||Use a concentration of 1 µg/ml.|
|ELISA||Use at an assay dependent dilution.|
IHC image of Histone H3 (tri methyl K9, di methyl K9) staining in Human normal skin formalin fixed paraffin embedded tissue section, performed on a Leica BondTM 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 ab71604, 1µg/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.
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.
Overlay histogram showing HeLa cells stained with ab71604 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab71604, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was a goat anti-mouse DyLight® 488 (IgG; H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
All batches of ab71604 are tested in Peptide Array against peptides to different Histone H3 modifications at 2µg/ml. Six dilutions of each peptide are printed on to the Peptide Array in triplicate and results are averaged before being plotted on to a graph. Results show strong binding to Histone H3 - tri methyl K9 peptide (ab1773) and di methyl K9 peptide (ab1772), indicating that this antibody recognises both modifications. Partial cross reactivity is observed with mono methyl K9 peptide (ab1771)
