US Patent 12071667 Sequence analysis using meta-stable nucleic acid molecules

The present disclosure relates in some aspects to methods for analyzing a target nucleic acid in a biological sample. In some aspects, the methods involve the use of a set of probe polynucleotides, for example a set of three or more probe polynucleotides, for assessing target nucleic acids. In some aspects, the presence, amount, and/or identity of region of interest in a target nucleic acid is analyzed in situ. Also provided are polynucleotides, sets of polynucleotides, compositions, and kits for use in accordance with the methods.
