This disclosure describes kits, reagents and methods for Recombinase Polymerase Amplification (RPA) of a target DNA that exploit the properties of recombinase and related proteins, to invade double-stranded DNA with single stranded homologous DNA permitting sequence specific priming of DNA polymerase reactions. The disclosed kits, reagents and methods have the advantage of not requiring thermocycling or thermophilic enzymes, thus offering easy and affordable implementation and portability relative to other amplification methods.

The invention relates to a method for modifying a template double stranded polynucleotide, especially for characterisation using nanopore sequencing. The method produces from the template a plurality of modified double stranded polynucleotides. These modified polynucleotides can then be characterised.

The invention describes a kit for detection of a target polynucleotide using a CRISPR effector system that comprises CAS9 from Francisella novicida, a synthetic sgRNA and a detection scheme based on binding and subsequent enzymatic cleavage of the target polynucleotide. The invention also describes a method for detection of a target polynucleotide using the kit. The kit can be .sub.el applied to both pathogenic and non-pathogenic polynucleotides and can be used to distinguish polynucleotides different by a single mismatch without the need for sequencing. The kit can also be used for detection of COVID-19. The kit is economical, easy to assemble and provides a robust and rapid readout that can be appropriately adapted for point of care applications.
