Sorry not to reply thru e-mail. My mailer seems to refuse to talk to your

I thought there have been some recent papers showing that the phage T7
promoter has unexpectedly good activity in eukaryotic tissues owing to a
similarity to the initiator element in eukryotic promoters. If so T7 is
only 20 bp. Might be worthwhile checking on Medline.
