- Cross reactivity of the antibody against Pol IIS2p To test the specificity an ELISA was performed using a serial dilution of the antibody against Pol IIS2p. The wells were coated with peptides containing the unmodified C-terminal repeat sequence as well as different phosphorylated peptides. Image shows the specificity of the antibody for the S2 phosphorylation.

- HeLa cells were stained with the antibody against Pol II S2p and with DAPI. Cells were fixed with methanol and blocked with PBS/TX-100 containing 5% normal goat serum and 1% BSA. The cells were immunofluorescently labelled with the Pol II S2p antibody (left) diluted 1:500 in blocking solution followed by an anti-mouse antibody conjugated to Alexa594. The middle panel shows staining of the nuclei with DAPI. A merge of the two stainings is shown on the right.

- ChIP was performed on sheared chromatin from 1 million HeLaS3 cells using 1 ug of the ab against Pol II S2p. The IP'd DNA was subsequently analysed on an Illumina Genome Analyzer. The 36 bp tags were aligned to the human genome using the ELAND algorithm. Image shows the peak distribution along the complete sequence and a 150 kb region of the X-chromosome (figure 2A and B, respectively), and in a two genomic regions surrounding the GAPDH and ACTB positive control genes (figure 2C and D).

- ChIP assays using HeLa cells & Pol II S2p ab. ChIP-seq kit , using sheared chromatin from 1 million cells. A titration of 1, 2, 5 and 10 ug of ab was used. IgG (2 ug/IP) was negative control. qPCR was with primers specific for the coding region of the constitutively expressed GAPDH and ACTB as positive controls, and for exon 2 of the inactive myoglobin (MB) gene and the Sat2 satellite repeat as negative controls. Image shows the recovery, expressed as a % of input (the relative amount of IP'd DNA compared to input DNA after qPCR).
