Recombinase Aided Amplification for real-time fluorescence detection

Intended Purpose

(RT-)RAA Nucleic Acid Amplification Kit (Fluorescent Method) can be used to amplify nucleic acids. The amplification result can be verified by use of fluorescent probes in real-time.

 

Advantages

Rapid amplification and real-time detection

RAA technology amplifies RNA and DNA in just a few minutes. Positive amplification results are usually detectable after 3 to 10 minutes incubation, provided an appropriate fluorescence reader is used for incubation.

 

Aliquoted freeze-dried reagent mixes

Recombinase Aided Amplification kits are convient to handle. They comprise of freeze-dried enzyme mix aliquoted in standard 0.2mL PCR tubes and of two buffers for rehydration and starting the amplification reaction.

 

Reverse transcriptase included

In the RT-version of RAA kits, the reverse transcriptase enzyme is included in the freeze-dried reagent pellet. There is no extra pipetting step and no extra costs.

 

Recombinase Aided Amplification Kit (RAA and RPA)

 

Recombinase Aided Amplification (RAA) kits are manufactured by Jiangsu Qitian Gene Biotechnology Co., Ltd.

How to use

Protocol for fluorescent RAA assays:

  • prepare mastermix of reagents buffer, magnesium acetate and primer-probe mix
  • open tube with freeze-dried reagents and add mastermix into the inner surface of the tube lid
  • add extracted nucleic acids to the lid as well
  • close tube, short-spin and mix by pulse-vortexing
  • place tube in your instrument and start incubation and detection (at approx. 37-42°C)
