Recombinase-aided isothermal nucleic acid amplification technology

Recombinase Aided Amplification

RAA technology is short for Recombinase Aided Amplification, a technology that uses recombinase, single-stranded binding protein, and DNA polymerase under isothermal conditions (optimal temperature 39℃) to amplify nucleic acids. The specific principle is: recombinase, single-stranded binding protein, and primers form a polymer that scans double-stranded DNA. At the sequence homologous to the primer, the double-stranded DNA is unwound, the single-stranded binding protein (SSB) binds to the unwound single strand to prevent the renaturation of single-stranded DNA, and in the presence of energy and dNTP, the DNA polymerase completes the chain extension.

Isothermal Amplification Breakthrough: RAA Platform Accelerates Chikungunya Virus Research

Since 2025, Chikungunya virus (CHIKV) has shown exceptionally active spread in tropical regions. Although traditional RT-PCR offers high sensitivity, its >2-hour amplification cycle and heavy reliance on specialized equipment have created bottlenecks for research teams needing critical data during outbreaks. Field traceability studies are further constrained by cold-chain transport requirements and laboratory dependencies.

Literature sharing: Rapid detection of Salmonella with Recombinase Aided Amplification

This year, the theme of World Food Safety Day is science in action. As innovation determines the future, science and technology are crucial in ensuring food safety. Rapid detection of foodborne pathogens has always been a key link in food safety prevention and control. As the most common pathogen causing food poisoning worldwide, the innovation of Salmonella detection technology has significant public health implications. This study introduces a recombinase-aided isothermal nucleic acid amplification method for rapid Salmonella detection that can complete the entire testing process within 20 minutes.
