Western blot was performed on whole cell (25 \u00b5g, lane 1) and histone extracts (15 \u00b5g, lane 2) from HeLa cells, and on 1 \u00b5g of recombinant histone H2A, H2B, H3 and H4 (lane 3, 4, 5 and 6, respectively) using the Bioss antibody against H3K9me3 (Cat. No. bs-53114R). The antibody was diluted 1:1,000 in TBS-Tween containing 5% skimmed milk.
HeLa cells were stained with the Bioss antibody against H3K9me3 (bs-53114R) and with DAPI. Cells were fixed with 4% formaldehyde for 10\u2019 and blocked with PBS\/TX-100 containing 5% normal goat serum and 1% BSA. The cells were immunofluorescently labeled with the H3K9me3 antibody (middle) diluted 1:1,000 in blocking solution followed by an anti-rabbit antibody conjugated to Alexa488. The left panel shows staining of the nuclei with DAPI. A merge of both stainings is shown on the right.
To determine the titer of the antibody, an ELISA was performed using a serial dilution of the antibody directed against human H3K9me3 (bs-53114R) in antigen-coated wells. The antigen used was a peptide containing the histone modification of interest. By plotting the absorbance against the antibody dilution, the titer of the antibody was estimated to be 1:30,000.
A Dot Blot analysis was performed to test the cross-reactivity of the antibody against H3K9me3 (Cat. No. bs-53114R) with peptides containing other modifications and unmodified sequences of histone H3 and H4. One hundred to 0.2 pmol of the peptide containing the respective histone modification were spotted on a membrane. The antibody was used at a dilution of 1:20,000. The figure shows a high specificity of the antibody for the modification of interest.

Western blot was performed on whole cell (25 \u03bcg, lane 1) and histone extracts (15 \u03bcg, lane 2) from HeLa cells, and on 1 \u03bcg of recombinant histone H2A, H2B, H3 and H4 (lane 3, 4, 5 and 6, respectively) using the Bioss antibody against H3K27me3 (Cat.

A Dot Blot analysis was performed to test the cross-reactivity of the Bioss antibody against H3K27me3 (Cat. No. bs-53122R) with peptides containing other modifications of histone H3 and H4 and the unmodified H3K27 sequence. One hundred to 0.2 pmol of the peptide containing the respective histone modification were spotted on a membrane. The antibody was used at a dilution of 1:5,000. Figure 4 shows a high specificity of the antibody for the modification of interest. Please note that that antibody also recognizes the modification if S28 is phosphorylated.
Mouse NIH3T3 cells were stained with the Bioss antibody against H3K27me3 (Cat. No. bs-53122R) and with DAPI.

Western blot using the TAF1 antibody (bs-53045R) to detect TAF1 in HeLa nuclear extract (arrowhead). The membrane was probed with the primary antibody at dilutions of 1:100 (lane 1), 1:250 (lane 2), 1: 500 (Lane 3) and 1:1,000 (Lane 4). The identity of the bands at ~95 kDa is unknown but may be degraded TAF1.

Whole cell extracts from HeLa cells (25 \u03bcg) were analysed by Western blot using the H3pan antibody (bs-53074R) diluted 1:500 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is indicated on the right; the marker (in kDa) is shown on the left.
ChIP assays were performed using human HeLa cells, the Diagenode antibody against H3pan (bs-53074R) and optimized PCR primer sets for qPCR. ChIP was performed using sheared chromatin from 1 million cells. A titration of the antibody consisting of 1, 2, 5, and 10 \u03bcl per ChIP experiment was analysed. IgG (2 \u03bcg\/IP) was used as negative IP control. QPCR was performed with primers for the promoters of the active GAPDH and EIF4A2 genes, used as negative controls, and for the inactive MYOD1 and the Sat2 satellite repeat, used as positive controls. The figure shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).
To determine the titer of the antibody, an ELISA was performed using a serial dilution of the H3pan antibody (bs-53074R). The plates were coated with the peptides used for immunization. By plotting the absorbance against the antibody dilution, the titer of the antibody was estimated to be >1:1,000,000.
