In vitro runoff transcription of PW and PX. PCR products containing either PW or PX were used as templates for runoff transcription reactions with core RNAP either alone (−) or after supplementation with either ςX (X) or ςW (W). Note that the core RNAP preparation has a low level of activity in the absence of added ς, suggesting that this preparation has some contaminating ςX as noted previously (15).
