The ig® RPA Kit from Intact Genomics gives the user a faster, more streamlined Recombinase Polymerase Amplification experience by providing the necessary reagents and enzymes to amplify user-provided DNA template. Isothermal RPA is an enhancement over PCR amplification because it does not require thermocycling and provides better sensitivity.  

Recombinase Polymerase Amplification (RPA) is a molecular biology technique that amplifies DNA at a constant temperature (37-42°C) using a recombinase (e.g. UvsX), primers, a single-stranded DNA binding protein (SSB), and a strand displacing DNA polymerase. T4 UvsX is used in combination with its accessory protein, UvsY. The recombinase interacts with the primers to form nucleoprotein filament. This complex can bind with homologous double-stranded DNA through a strand exchange. After the exchange, a single-stranded binding protein, T4 gp32, stabilizes the displaced strand. Finally, Bsu/Sau DNA polymerase extends the DNA from the primers and creates a new complete copy of the template. Amplification can continue as in Polymerase Chain Reaction (PCR).

Additional information


25 Reactions, 100 Reactions

  1. Mix Positive Control with enzyme mixture thoroughly then add 2x RPA Reaction mix.

RPA Table

  1. To initiate the reaction, add 1 µl of MgOAc, mix thoroughly, and pulse spin the reaction tube.
  2. Incubate the tube at 38°C for 15-60 minutes. The reaction may also be performed at ambient temperature. However, we recommend increasing the incubation time to a minimum of 30 minutes.
  3. Purify the DNA via ethanol precipitation (or the user’s preferred method). Analyze the DNA by gel electrophoresis on a 1% agarose gel (or up to 2% agarose gel).
