Abstract
This disclosure describes related novel 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 methods have the advantage of not requiring thermocycling or thermophilic enzymes. Further, the improved processivity of the disclosed methods may allow amplification of DNA up to hundres of megabases in length.
Claims21
A dried recombinase polymerase amplification (RPA) reagent composition comprising:
- (1) at least one recombinase;
- (2) at least one polymerase;
- (3) trehalose;
- and
- (4) a crowding agent.
