Association and dissociation of telomerase and
2′-O-meRNA 1. (A) Rate of
telomerase inhibition upon addition of 2′-O-meRNA
1. 2′-O-meRNA 1 (333 nM) was added
to telomerase-containing cell extract for the time indicated (0, 0.5,
1, 3, 5, 8, or 10 min) before initiation of strand elongation.
(B) Stability of inhibition by 2′-O-meRNA
1. Telomerase was incubated with 100 nM
2′-O-meRNA 1 for 30 min to ensure complete
inhibition. Competitor DNA (5.0 μM final concentration) complementary
to 1 was then added for 0, 10, or 20 min before the assay
for telomerase activity.
