Assay Conditions: ChIP results obtained with the antibody directed against H2AK5ac
ChIP assays were performed using human HeLa cells, the antibody against H2AK5ac (Cat. No. 25230) and optimized PCR primer sets for qPCR. ChIP was performed using sheared chromatin from 1.5 million cells. A titration of the antibody consisting of 0.5, 1, 2 and, 5 µg per ChIP experiment was analysed. IgG (1 µg/IP) was used as negative IP control. QPCR was performed with primers for a region approximately 1 kb upstream of the GAPDH and ACTB promoters, used as positive controls, and for the coding region of the inactive MYOD1 gene and the Sat2 satellite repeat, used as negative controls. Figure 1 shows the recovery, expressed as a % of input (the relative amount of immunoprecipitated DNA compared to input DNA after qPCR analysis).ChIP-seq results obtained with the antibody directed against H2AK5ac
ChIP was performed on sheared chromatin from 1.5 million HeLaS3 cells using 0.5 µg of the antibody against H2AK5ac (Cat. No. 25230) as described above. The immunoprecipitated DNA was subsequently analysed on an llumina HiSeq. Library preparation, cluster generation and sequencing were performed according to the manufacturer's instructions. The 51 bp tags were aligned to he human genome using the BWA algorithm. Figure 2 shows the enrichment along the complete sequence and a 1 Mb region of the X-chromosome (fig 2A and B) and in genomic regions of chromosome 7, surrounding the ACTB gene, and of chromosome 12, surrounding the GAPDH gene (fig 2C and D). The position of the amplicon used for ChIP-qPCR is indicated by an arrow.Determination of the antibody titer
To determine the titer of the antibody, an ELISA was performed using a serial dilution of the antibody directed against H2AK5ac (Cat. No. 25230) 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 1:25,000.Cross reactivity tests using the antibody directed against H2AK5ac
To test the cross reactivity of the antibody against H2AK5ac (Cat. No. 25230), a Dot Blot analysis was performed with peptides containing other histone modifications and the unmodified H2AK5. One hundred to 0.2 pmol of the respective peptides were spotted on a membrane. The antibody was used at a dilution of 1:5,000. Figure 3 shows a high specificity of the antibody for the modification of interest.Western blot analysis using the antibody directed against H2AK5ac
Western blot was performed on whole cell (25 µg, lane 1) and histone extracts (15 µg, lane 2) from HeLa cells, and on 1 µg of recombinant histone H2A, H2B, H3 and H4 (lane 3, 4, 5 and 6, respectively) using the antibody against H2AK5ac (Cat. No. 25230). The antibody was diluted 1:1,000 in TBS-Tween containing 5% skimmed milk. The marker (in kDa) is shown on the left.
