P55 Subunit of Human Transcription Factor II A antibody

Antigen: P55 Subunit of Human Transcription Factor II A

Clonality: Polyclonal

Host: Rabbit

Reactivity: Human

Application: Western Blotting (WB)

Catalog no.: ABIN123787

Additional Information

Format: Liquid

Description: 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 (alpha-subunit), 19 kDa (beta-subunit) and 12 kDa (gamma-subunit). The alpha- and beta-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 (gamma-subunit), retains native TFIIA activity. alpha-TFIIA is an affinity-purified rabbit polyclonal antibody raised against a recombinant full-length p55 subunit of the TFIIA complex.

Specificity: Alpha-TFIIA reacts with the p55 protein in HeLa nuclear extract by Western blotting.
