The Phospho-POLR2A-S2 Monoclonal Antibody (CABP0996) 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, IF/ICC, ChIP, ChIP-seq, ELISA, CUT&Tag applications and has demonstrated reactivity against Human, Mouse, Rat samples.
