||Tandem Affinity Purification (TAP) tags and dot blot analysis have been used to measure the amounts of RNA polymerase II transcription proteins in crude yeast extracts.
||The measurements showed comparable amounts of RNA polymerase II, TFIIE, and TFIIF, lower levels of TBP and TFIIB, and still lower levels of Mediator and TFIIH.
