Description

General description

RNA polymerase II (Pol II) is a multi-subunit enzyme responsible for the transcription of protein-coding genes. Transcription initiation requires recruitment of the complete transcription machinery to a promoter via solicitation by activators and chromatin remodeling factors. Pol II can coordinate 10 to 14 subunits. This complex interacts with the promoter regions of genes and a variety of elements and transcription factors. The DNA binding domain of the polymerase is a groove where TFIIB orients the DNA for unwinding and transcription.

Specificity

This antibody recognizes Phospho- and non-phospho-RNA polymerase II.

Immunogen

Peptide containing 10 repeats of YSPT[pS]PS corresponding to the carboxyl-terminal domain of RNA polymerase II.

Application

Anti-RNA polymerase II Antibody, clone CTD4H8 is a high quality Mouse Monoclonal Antibody for the detection of RNA polymerase II and has been published in more than 40 citations and validated for use in ChIP & WB.

Physical form

Format: Purified

Protein G Chromatography

Purified mouse IgG1 in buffer containing 0.1M Tris-glycine, pH 7.4, 0.15M NaCl, 0.05% sodium azide before the addition of glycerol to 30%.

Storage and Stability

Stable for 1 year at -20°C from date of receipt.

Handling Recommendations:
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.

Analysis Note

Control
A431 nuclear extract.
