A mutation analysis method based upon a wild-type DNA sequence is presented. Oligonucleotides were utilized for primer extension by T7 DNA polymerase to discriminate between wild-type and mutant sequences in two solid phase approaches. 1. Oligonucleotides were annealed to an immobilized template, ex

β¦ Synopsis
We have developed a solid phase chemical cleavage method (SpCCM) for screening large DNA fragments for mutations. All reactions can be carried out in microtiterwells from the first amplification of the patient (or test) DNA through the search for mutations. The reaction time is significantly reduced compared to the conventional chemical cleavage method (CCM), and even by using a uniformly labelled probe, the exact position and nature of the mutation can be revealed. The SpCCM is suitable for automatization using a workstation to carry out the reactions and a fluorescent detection-based DNA sequencing system to analyze the cleaved fragments.
