In vitro transcription
of pUPDR2, pUPDR2/hU6 and pUPDR2-Expression in
the presence of TBPwt or TBP-DR2 respectively. In vitro transcription
was performed and the positions of the individual transcripts are
indicated. Three transcription samples of each template (lanes 1–3,
pUPDR2; lanes 4–6, pUPDR2-Expression; lanes
7–9, pUPDR2/hU6) were analysed in a
transcription system based on 10 µl
phosphocellulose fraction B plus 20 µl
phosphocellulose fraction C (lanes 1, 4 and 7) and were supplemented
with either 20 ng TBP-DR2 (lanes 2, 5 and 8) or 20 ng TBPwt (lanes
3, 6 and 9).
