Abstract
To realize an ultra sensitive determination of specific DNA, we developed and optimized on-bead rolling circle amplification (RCA) method for quantitative analyses. By using agarose beads, detection efficiency increased 100 times compared to the conventional RCA method, and quantitative analyses of 1 μL of samples containing 0.05 - 1.0 nM DNA were realized.
