Ten repeats of synthetic peptide YSPTSPS with phosphorylated serine 5 was used as the immunogen for the recombinant Phospho-RNA Polymerase II CTD Repeat YSPTSPS antibody.
RNA polymerase II (Pol II) is an enzyme that is composed of 12 subunits and is responsible for the transcription of protein-coding genes. Transcription initiation requires Pol II-mediated recruitment of transcription machinery to a target promoter, there
