The Phospho-POLR2A-S7 Antibody (CABP0969) is a high-quality antibody developed for reliable detection and analysis of target proteins. This gene encodes the largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. The product of this gene 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, this subunit, in combination with several other polymerase subunits, forms the DNA binding domain of the polymerase, a groove in which the DNA template is transcribed into RNA.
This antibody is validated for use in WB, IHC-P, ChIP, ELISA applications and has demonstrated reactivity against Human, Mouse, Rat samples.

Western blot analysis of lysates from MCF7 cells, using Phospho-POLR2A CTD-S7 Rabbit pAb (CABP0969) at 1:1000 dilution. MCF7 cells were treated with Doxorubicin (0. 5 uM) at 37℃ for 24 hours. MCF7 cells were treated with nocodazole (50 ng/ml) at 37℃ for 20 hours. Secondary antibody: HRP-conjugated Goat anti-Rabbit IgG (H+L) (AS014) at 1:10000 dilution. Lysates/proteins: 25μg per lane. Blocking buffer: 3% nonfat dry milk in TBST. Detection: ECL Basic Kit (AbGn00020). Exposure time: 1s.
Immunohistochemistry analysis of paraffin-embedded Human colon carcinoma using Phospho-POLR2A CTD-S7 Rabbit pAb (CABP0969) at dilution of 1:200 (40x lens). High pressure antigen retrieval performed with 0.01M Citrate buffer (pH 6.0) prior to IHC staining.
Immunohistochemistry analysis of paraffin-embedded Rat brain using Phospho-POLR2A CTD-S7 Rabbit pAb (CABP0969) at dilution of 1:200 (40x lens). High pressure antigen retrieval performed with 0.01M Citrate buffer (pH 6.0) prior to IHC staining.
Chromatin immunoprecipitation was performed with cross-linked chromatin from HeLa cells, using Phospho-POLR2A CTD-S7 Rabbit pAb (CABP0969) and rabbit IgG (AC005). The amount of immunoprecipitated DNA was checked by quantitative PCR. Histogram compares the ratio of the immunoprecipitated DNA versus the input.
