CXXC1 Antibody - ChIP-seq Grade (sample size)

Figure 1. ChIP results obtained with the Diagenode antibody directed against CXXC1
ChIP assays were performed using HeLa cells, the Diagenode antibody against CXXC1 (Cat. No. C15410315) and optimized PCR primer sets for qPCR. ChIP was performed with the “iDeal ChIP-seq” kit (Cat. No. C01010055), using sheared chromatin from 4 million cells. A titration consisting of 1, 2 and 5 μg of antibody per ChIP experiment was analyzed. IgG (2 μg/IP) was used as a negative IP control. Quantitative PCR was performed with primers for the active EIF4A2 and GAPDH promoters, used as positive controls, and for 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).

Figure 2. ChIP-seq results obtained with the Diagenode antibody directed against CXXC1
ChIP was performed on sheared chromatin from 4,000,000 HeLa cells using 2 μg of the Diagenode antibody against CXXC1 (Cat. No. C15410315) as described above. The IP’d DNA was subsequently analysed on an Illumina HiSeq 2000. Library preparation, cluster generation and sequencing were performed according to the manufacturer’s instructions. The 50 bp tags were aligned to the human genome using the BWA algorithm. Figure 2 shows the peak distribution along the complete sequence and an 800 kb region of chromosome 1 (figure 2A and B) and in two regions surrounding the EIF4A2 and GAPDH positive control genes, respectively (figure 2C and D).

Figure 3. Western blot analysis using the Diagenode antibody directed against CXXC1
Whole cell extracts from HeLa cells were analysed by Western blot using the Diagenode antibody against CXXC1 (Cat. No. C15410315). The antibody was diluted 1:1,000 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.

Figure 4. Immunofluorescence using the Diagenode antibody directed against CXXC1
A549 cells were stained with the Diagenode antibody against CXXC1 (Cat. No. C15410315) diluted 1:100. The right picture shows costaining with DAPI.
