HeLa cells were treated with TSA (figure on left) or with colcemid (figure on right), and 15 μg of histone extracts of these cells were analyzed by Western blot using the antibody against H3S10p (bs-53069R) diluted 1:500 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is indicated on the left; the marker (in kDa) is shown on the right. The result of the Western analysis with the antibody is shown in lane 1; lane 2 shows the same analysis after incubation of the antibody with 750 pmol blocking peptide for 1 hour at room temperature.
