Abstract excerpt
A new approach is presented for the sensitive and selective scanning for unknown DNA mutations, based on ligation-mediated PCR and the use of the glycosylases TDG and MutY. These two highly selective enzymes together can detect about 70% of commonly observed polymorphisms and mutations in human tumors. DNA is cross-hybridized to form mismatches at the positions of point mutations, de-phosphorylated to eliminate...
