Abstract: Described is an assay termed Programmable Enzyme-Assisted Selective Exponential Amplification (PASEA) that concurrently amplifies both wild type and mutant alleles while selectively cleaving the former. With time, the rare mutant alleles dominate, and are readily detectable by direct detection, Sanger sequencing, and other readily available methods. Also described are point-of-care assays and microfluidic devices for performing PASEA.

Abstract: Disclosed herein are methods for multiple stage isothermal amplification of nucleic acid comprising a first substantially isothermal amplification reaction on the nucleic acid to generate a first amplification product and at least one substantially isothermal amplification reaction on the first amplification product to generate at least one second amplification product in an amount sufficient for recovery, testing, or characterization.

Abstract: Provided are methods directed to enriching nucleic acids in a biological sample. These methods, in some embodiments can discriminately enrich the abundance of low-copy nucleic acids relative to higher-copy nucleic acids. In some embodiments, the methods provided can enrich a low-copy number mutant allele associated with a disease state, thus allowing early detection and optimized treatment. In other embodiments, the methods can be used for detection of particular molecules, such as antigens, in a sample.
