Immobilized template assays
WitrynaHere we employed immobilized template assays to correlate transcriptional activation with mediator and TFIID recruitment. In reactions reconstituted with purified proteins, we found that activator, TFIID, and mediator engage in reciprocal cooperative interactions to form a complex on promoter DNA. Witryna9 paź 2007 · Immobilized template assays were performed by incubating the indicated nuclear extracts with the HIS4 immobilized template for 40 min in the presence of Gal4-AH (1.5 pmol) (lanes 2–4). In lane 1, Dynabeads lacking DNA were incubated with Gal4-AH and nuclear extract.
