Extra Details:: Transcription factor IIF (TFIIF) is a heterodimer, com- posed of 58kD (RAP74) and 26kD (RAP30) subunits. It was first identified through the ability to interact with immobilized RNA polymerase II. In addition to its role in transcription initiation, TFIIF can increase the specificity and efficiency of RNA polymerase II transcription, and can especially increase the rate of transcription elongation. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:200-1:1000 Optimal dilutions to be determined by the researcher.
