Anti -TFIIEb (anti-p34) antibody

The human Transcription Factor IIE (TFIIE) is composed of 56 kDa (α) and 34 kDa (β) subunits and is shown to be a heterotetramer (1, 2). The 56-kDa subunit contains a region similar to a zinc-binding domain and a region sharing homology with the catalytic loop of a kinase domain (3). TFIIE binds to RNA polymerase II in solution and joins the preinitiation complex probably concomitant with RNA polymerase II and TFIIF (4).

Each vial contains 100 μg IgG in 0.1 ml of PBS.

Specificity
α-TFIIE reacts with the p34 protein in HeLa nuclear extract by Western Blotting. Recommended dilution range for Western blot analysis: 1:2000-1:5000. Recommended starting dilution: 1:2000.

Storage
Aliquot and store at –20°C.
