In this study, a lateral flow dipstick recombinase polymerase amplification (LFD-RPA) assay for rapid detection of both hemagglutinin and neuraminidase gene of H7N9 was developed and evaluated. The H7-LFD-RPA and N9-LFD-RPA assay were able to detect 32 fg H7N9 nucleic acid which is more convenient and rapid than previous methods.
A paper chip device-based recombinase polymerase amplification (RPA) method was developed for highly sensitive and selective single-step detection of foodborne pathogens. The diagnostic utility of the device was demonstrated by the reliable detection of E. coli and S.aureus present in spiked milk. This ready-to-use device could be integrated with simple nucleic acid extraction for food pathogen detection in resource-limited settings.
The RPA-LFD assay was highly sensitive, detecting down to 10 copies of plasmid DNA. There was no cross-reactivity with other pathogens causing vesicular lesions. In addition, 143 clinical samples were used to compare RPA-LFD with real-time PCR, with 98.6% concordance between the assays. Therefore, the developed RPA-LFD assay provides a rapid, simple, highly promising approach to be used as point-of-care
RPA has been validated on over 200 infected strawberry plants with a diagnostic sensitivity of 93% and a diagnostic specificity of 99%, respectively. Together, this work demonstrates the value of using new approaches to identify loci for detection and provides valuable diagnostic tools that can be used to monitor soil and strawberry plant samples for M. phaseolina.
In this study, isothermal recombinase polymerase amplification (RPA) was combined with unmodified gold nanoparticles (AuNPs) to detect Salmonella in milk. A rapid, effective, visualized, and low-cost RPA-AuNP assay was developed, with a detection limit of 50 CFU for milk samples after enrichment for 6 h or 1 pg for DNA within 15 min at 37 C using simple water bath

An integrated sample-in-digital-answer-out (SIDAO) diagnostic system incorporating DNA extraction and digital recombinase polymerase amplification, which enables rapid and quantitative nucleic acid analysis from bodily fluids within a disposable cartridge.
The data provided here describe the information for designing primers and probes for LAMP and RPA, how specific they are for each of the three fungi, and the evaluation of RPA on field samples.
A reverse transcription recombinase polymerase amplification (RT-RPA) assay was developed to detect TMEV infection. The sensitivity of the RT-RPA assay approached 8 copies per reaction, which is equivalent to the sensitivity of RT-qPCR reactions.
Rapid diagnosis of Mycobacterium tuberculosis (Mtb) is key to controlling the spread of tuberculosis, which is a global health concern. In this study, isothermal recombinase polymerase amplification (RPA) was developed to detect specific targets of Mtb, IS6110 and IS1081. Additionally, SYBR Green I was used for endpoint detection of the RPA products by the naked eye.
