Synthetic peptide corresponding to Human Histone H2A.X aa 100 to the C-terminus (C terminal) conjugated to Keyhole Limpet Haemocyanin (KLH). Synthetic peptide derived from residues 100 - 200 of Human H2A.X.
Our Abpromise guarantee covers the use of ab10475 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/500 - 1/1000. Detects a band of approximately 15 kDa (predicted molecular weight: 15 kDa).|
|IHC-P||Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
WB using ab10475
IHC image of Histone H2A X staining in human B cell lymphoma FFPE section, performed on a 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 ab10475, 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.
HeLa cells were incubated at 37°C for 3h with vehicle control (0 µM) and different concentrations of camptothecin (ab120115). Increased expression of γH2A.X (phospho S139) in HeLa cells correlates with an increase in camptothecin concentration, as described in literature.
Whole cell lysates were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 20µg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 5% BSA before being incubated with ab2893 at 1 µg/ml and ab10475 at 1 µg/ml overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP (ab97051) at 1/10000 dilution and visualised using ECL development solution.
