DATASHEET

Host: Rabbit

Target Protein: POLR2A

Modification Site: Ser2

Clonality: Recombinant

Isotype: IgG

Entrez Gene: 5430

Swiss Prot: P24928

Source: KLH conjugated synthetic peptide derived from human POLR2A around the phosphorylation site of S2

Purification: Purified by Protein A.

Storage Buffer: 0.01M TBS (pH 7.4), 1% BSA, 0.02% Proclin 300, and 50% Glycerol

Storage: Shipped at 4C. Store at -20C for one year. Avoid repeated freeze/thaw cycles.

Background:

During transcription elongation, Pol II moves on the template as the transcript elongates. Elongation is influenced by the phosphorylation status of the C-terminal domain (CTD) of Pol II largest subunit (RPB1), which serves as a platform for assembly of factors that regulate transcription initiation, elongation, termination and mRNA processing.

Size: 100µL

Concentration: Lot dependent

Predicted Molecular Weight: 217


Cross Reactive Species: Human
Mouse
Rat

VALIDATION IMAGES

4% Paraformaldehyde-fixed Hela (H) cell; Triton X-100 at r.t. for 20 min; Antibody incubation with (Phospho-POLR2A (Ser2)) monoclonal Antibody, unconjugated (bsm-62939R) 1:100, 90 min at 37°C; followed by conjugated Goat Anti-Rabbit IgG antibody (green, bs-60295G-FITC) at 37°C for 90 min, DAPI (blue, C02-04002) was used to stain the cell nuclei. PBS instead of the primary antibody was used as the blank control.
