Table 2. Sequences and binding and priming activities of selected round 9 aptamers.

^aCompetition efficiency as determined by the reduction of ³²P-labelled wt-Dε RNA bound to P: +++, wt-like (40–50% reduction); ++++, > wt (65–85% reduction); ++, < wt (25–30% reduction); +, << wt (<15% reduction); +/− no detectable reduction. ^bCerenkov cpm of ³²P-labelled RNA remaining bound to P after four washings; nd, not determined. ^cRelative intensity of priming signals. ++, wt-like; +++, > wt; +, < wt; −, no signal above background.
