Phospho-RNA pol II CTD (Ser2) Antibody (14-9802-82) in ICC/IF
Immunofluorescence analysis of Phospho-POLR2A (Ser2) Monoclonal Antibody (Product # 14-9802-82) was performed using 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 30 minutes at 37°C, and blocked with 10% Normal Goat Serum for 1 hour at room temperature. The cells were labeled with 1.25 µg/mL of Ph... View More

产品详细信息
Description: This 3E10 monoclonal antibody recognizes a specific phosphorylated form of RNA polymerase II subunit B1 (RPB1). It detects phosphorylated serine at amino acid position 2 (Ser2) within the C-terminal heptapeptide (YSPTSPS) repeats of RPB1. Modifications within the C-terminal domain (CTD) of RPB1 recruit RNA processing factors that govern the transcription cycle; phosphorylation at Ser2 is associated with transcriptional elongation. The 3E10 immunogen was an ovalbumin-conjugated peptide corresponding to human RPB1 CTD phosphorylated at Ser2 (YS(p)PTSPSYSPTSPSC).
Applications Reported: This 3E10 antibody has been reported for use in western blot and immunocytochemistry.
Applications Tested: This 3E10 antibody has been tested by western blot of human, mouse, and rat cell lysates and immunocytochemistry of human cell lines. This may be used at less than or equal to 2.0 µg/mL for western blot and less than or equal to 1.25 µg/mL for immunocytochemistry.
靶标信息
RNA polymerase II is the enzyme responsible for the synthesis of mRNA and many non-coding RNAs. POLR2A encodes RNA polymerase II subunit B1 (RPB1), the largest subunit of RNA polymerase II. The C-terminal domain (CTD) of RPB1 contains tandem heptapeptide repeats with the consensus sequence YSPTSPS. Phosphorylation and other modifications within this sequence influence the recruitment of factors that regulate the transcription cycle. Recruitment of RNA processing factors to the elongation complex is coordinated by the phosphorylation of Serine-2 and Serine-5 residues within the CTD.
