Electropherograms after successive short injections of H63D heterozygous mutant DNA that show the change of ssDNA to dsDNA in the channels after leaving the formamide-rich environment of the sample well. (fluorescence in relative fluorescence units (RFU) vs. time). a) H63D immediately after a 60 s injection. b) H63D after a subsequent 10 s injection c) H63D after a second subsequent 10 s injection
