Kinetics of hairpin to duplex conversion for (CAG)10 and (CTG)10, LP1, LP2, ST1, or LP1/ST1. A, autoradiogram revealing conversion of (CAG)10 hairpin to (CAG)10/(CTG)10 duplex after incubation at 37 °C. B, graphical representation of percent duplex product as a function of time for (CAG)10 and (CTG)10 (closed circles), (CAG)10 and LP1 (open circles), (CAG)10 and LP2 (closed triangles), (CAG)10 and ST1 (open diamonds), or (CAG)10 and LP1/ST1 (open squares).
