  • Publication number: 20210164016
    Abstract: Methods and materials are provided for detecting nucleic acid sequence differences including single nucleotide mutations or polymorphisms, one or more nucleotide insertions, and one or more nucleotide deletions in single molecule target members present in a test population of nucleic acid fragments. Heteroduplexes are formed between members of the test nucleic acid population and their corresponding complements provided in a pool of mismatch cleavage probes. Mismatched base pairs in the heteroduplexes are specifically cleaved and cleaved probe fragments are electronically detected to signal the present of the target members in the test population.
