The invention includes methods and apparatus for separating mutations, especially rare and unknown mutations, using heteroduplex binding proteins. Nucleic acids may optionally be nicked at or near the mutation in order to promote heteroduplex binding protein recognition and binding. In particular, using the disclosed methods, it is possible to separate heteroduplexed nucleic acid strand pair from homoduplexed nucleic acid strand pairs having similar sequences and being at a much higher concentration. Once the heteroduplexed nucleic acids are isolated and recovered, it is straightforward to analyze the sequences of the heteroduplexed nucleic acids, e.g., using sequencing or hybrid assays.

Method for isolating target nucleic acid using heteroduplex binding proteins

The invention generally relates to sequencing library preparation methods. In certain embodiments, two template nucleic acids are joined together by a linking molecule, such as a PEG derivative. The linked template nucleic acids is amplified, creating linked amplicons.

Methods of sequencing with linked fragments

Methods and apparatus providing for the isolation of an unknown mutation from a sample comprising wild type nucleic acids and mutated nucleic acids through the application of time-varying driving fields and periodically varying mobility-altering fields to the sample within in an affinity matrix.
