Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly243 of human TFIIE-α protein. Antibodies are purified by protein A and peptide affinity chromatography.
Background
Transcription initiation factor IIE subunit alpha (TFIIE-α) is part of TFIIE, a general transcription factor made up of paired α and β subunits. These general transcription factors include TFIIA, TFIIB, TFIID, TFIIE, TFIIF, and TFIIH (1-4). Binding of RNA polymerase II (RNAPII) to promoter sequences as part of the pre-initiation complex (PIC) is facilitated by these general transcription factors. These factors also help in selection of the proper transcription start site, DNA unwinding, and RNAPII promoter escape during transcription (1). During the transition from transcription initiation to elongation, TFIIE stimulates the TFIIH kinase and DNA helicase activities, responsible for phosphorylation of the carboxy-terminal domain of the largest RNAPII subunit (POL2RA) and unwinding of promoter DNA for RNAPII promoter escape (1,5-9).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
