Endonuclease IV discriminates mismatches next to the apurinic/apyrimidinic site in DNA strands: constructing DNA sensing platforms with extremely high selectivity†
Abstract
A unique capability of Endonuclease IV in discrimination of mismatches neighboring a natural abasic site in DNA strands has been demonstrated, which enables genotyping of SNPs with high discrimination factors and differentiation of as low as 0.1–0.01% of target DNA strands from a large background of single-base different interfering strands.
