Figure 3From: Chemical cleavage reactions of DNA on solid support: application in mutation detectionDetection of T.C mismatch of 547 bp DNA fragment by using hydroxylamine / piperidine assay. The control trace (homoduplex, top) shows no cleavage peak and the mismatched DNA trace (heteroduplex, bottom) displays a strong cleavage peak of 5'FAM sequence at the mismatched C base. Note this is the second chance of detecting the mutation, the first being in Fig 2.Back to article page
