(A) An image
of primer extension on primer 1 at increasing concentrations
of 0.25, 0.5, 1, 2, 4, 8, 16 and 32 µM
and on primers 2 and 3 at increasing concentrations
of 8, 16 and 32 µM. (B)
A plot of relative fluorescence intensity of the Cy5-ddGTP-labeled
primers versus concentration. Each data point is the average of
the integral of five spots. Filled squares, primer 1;
filled triangles, primer 2; filled circles, primer 3.
