for RNA pol II CTD phospho Ser5 antibody (pAb)Background
RNA pol II (RNA polymerase II) is responsible for synthesizing messenger RNA in eukaryotes. RNA pol II contains a carboxy terminal domain composed of heptapeptide repeats that are essential for polymerase activity. These repeats contain serine and threonine residues that are phosphorylated in actively transcribing RNA polymerase. In addition, RNA pol II, in combination with several other polymerase subunits, form the DNA binding domain of the polymerase, a groove in which the DNA template is transcribed into RNA.
During the transcription cycle, the CTD of the large subunit of RNA pol II is reversibly phosphorylated. RNA pol II containing unphosphorylated CTD is recruited to the promoter, whereas the hyperphosphorylated CTD form is involved in active transcription. Phosphorylation occurs at two sites within the heptapeptide repeat, at Serine 5 and Serine 2. RNA pol II Serine 5 phosphorylation is confined to promoter regions and is necessary for the initiation of transcription.

RNA pol II CTD phospho Ser5 antibody tested by Western blot.
Nuclear extract of HeLa cells (20 µg) probed with RNA pol II CTD phospho Ser5 antibody at a dilution of 0.5 µg/ml.
RNA pol II CTD phospho Ser5 antibody tested by ChIP analysis.
Chromatin IP performed using the ChIP-IT® Express Kit (Catalog No. 53008) and HeLa Chromatin (1.5 x 10^6 cell equivalents per ChIP) using 10 µg of RNA pol II CTD phospho Ser5 antibody or the equivalent amount of rabbit IgG as a negative control. Real time, quantitative PCR (RT-qPCR) was performed on DNA purified from each of the ChIP reactions using a primer pair specific for the PABPC1 gene. Data are presented as Fold Enrichment of the ChIP antibody signal versus the negative control IgG (arbitrarily assigned a value of 1) using the ddCT method.
RNA pol II CTD phospho Ser5 pAb tested by dot blot analysis.
Dot blot analysis was used to confirm the specificity of RNA pol II CTD phospho Ser5 antibody for phospho-Ser5 of the RNA Pol II C-terminal domain heptad repeat. Modified and unmodified peptides were spotted onto PVDF and probed with the antibody at a dilution of 0.2 µg/ml. Decreasing amounts of peptide were spotted in each row.
Lane 1: Peptide phosphorylated at CTD repeat serine 2.
Lane 2: Unmodified CTD repeat serine 2 peptide.
Lane 3: Peptide phosphorylated at CTD repeat serine 5.
Lane 4: Unmodified CTD repeat serine 5 peptide.
