[Intact Genomics] Recombinase Polymerase Amplification

관리자 2023.03.23 14:26 조회 2137 추천 18


RPA, is it a good fit for your research?

Find out if RPA is right for your research and how to use it to potentially improve your end results via isothermal activity. Our newest resource takes a look into getting started with RPA, its benefits, and its general uses. Our Scientists have curated an informative new resource including multiple publications for those who are considering trying RPA.

What is RPA?


Recombinase Polymerase Amplification (RPA) is an enzyme- based alternative to Polymerase Chain Reaction (PCR) that amplifies isothermally. Like PCR, the primary objective of RPA is to make abundant copies of a targeted DNA sequence. Both PCR and RPA use a set of primers that target a DNA sequence of interest and a polymerase to make copies of that DNA sequence. RPA also achieves max amplification quicker than PCR.


We supply several publications and elaborate on the history and basic principles of this isothermal enzyme-based alternative to Polymerase Chain Reaction further in the article. Click below to read the full article and resources.

What Enzymes are needed?


We discuss the four enzymes needed (T4 UvsX DNA Polymerase, T4 UvsY Protein, T4 gp32 and Bsu DNA Polymerase) and their roles in the reaction.


Our team compiled over 30 publications that cover the history of RPA, uses of RPA, and options for optimization of RPA.
