- Extra Details:
- Transcription of naked DNA in vitro requires the general transcription factors and RNA polymerase II. However, this minimal set of factors is not sufficient for transcription when the DNA template is packaged into chromatin. Here, a factor that facilitates activator-dependent transcription initiation on chromatin templates was purified. This factor, remodeling and spacing factor (RSF), has adenosine triphosphate-dependent nucleosome-remodeling and spacing activities. Polymerases that initiate transcription with RSF can only extend their transcripts in the presence of FACT (facilitates chromatin transcription). Thus, the minimal factor requirements for activator-dependent transcription on chromatin templates in vitro have been defined. Applications: Suitable for use in ELISA, Western Blot and Immunoprecipitation. Other applications not tested. Recommended Dilutions: ELISA: 1:2000 Western Blot: 1:2000 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
