Figure 1. ChIP Chromatin Immunoprecipitation using the H3K27me3S28p antibody. Chromatin from one million formaldehyde cross-linked HeLa cells was used with 2 μg of H3K27me3S28p and 20 μl of magnetic IgG beads per immunoprecipitation. A no antibody (No Ab) control was also used. Immunoprecipitated DNA was quantified using quantitative PCR and normalized to the input chromatin.
Figure 2. Immunofluorescence Immunofluorescence of H3K27me3S28p antibody. Tissue: HeLa cells. Fixation: 0.5% PFA. Primary antibody used at a 1:200 dilution for 1 h at RT. Secondary antibody: Dylight 488 secondary antibody at 1:10,000 for 45 min at RT. Localization: Histone H3K27me3S28p is nuclear and chromosomal. Staining: Histone H3K27me3S28p is expressed in green, nuclei and alpha-tubulin are counterstained with DAPI (blue) and Dylight 550 (red).
