Anti -TFIIA (anti-p55) antibody

 The transcription factor IIA (TFIIA) has been shown to bind to the TBP-DNA complex and to increase the affinity of TBP for the TATA element. Human TFIIA consists of three subunits of 35 kDa (α subunit), 19 kDa (β subunit) and 12 kDa (γ subunit). The α and β subunits are derived from the product, p55, of a single gene by an unknown mechanism. However, recombinant p55, in combination with a 12 kDa subunit (γ subunit), retains native TFIIA activity (1-4).

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

Specificity
α-TFIIA reacts with the p55 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.
