We validated the RT-LAMP method in a hospital in China, employing 16 clinic samples with 8 positives and 8 negatives. The testing results are consistent with the conventional RT-qPCR. In addition, we also show that one-step process without RNA extraction is feasible to achieve RNA amplification directly from a sample.

Conventional RNA extraction is time-consuming and expensive; as such, this step is a major bottleneck during molecular diagnosis of viral infection. Here, we developed a simpliﬁed RT-LAMP using diluted and heat-treated crude serum samples; the assay NEB’s WarmStart LAMP Kit (DNA & RNA) provides fast LAMP/RT-LAMP results Experiments were designed to amplify a DNA target (BRCAb) and a RNA target (HMBS2) by LAMP or RT-LAMP, respectively. A 25 μl reaction containing 10 ng HeLa DNA or 5 ng Jurkat total RNA, 1X Master Mix, 1X LAMP primers and fluorescent dye was incubated on a Bio-Rad CFX98 instrument at 65°C for 75 minutes. 2019-12-01 · RT-LAMP amplification curves for log dilutions of PPRV Iran/2011 lineage IV (analysed in triplicate) are shown in Fig. 2. PPRV dilutions 10 -2 to 10 -4 showed fluorescence curves which were characterized by sharp peaks on the amplification rate plot ( Fig. 2 b), whereas the fluorescence curves for 10 -5 replicates are shallower and irregular in shape.

Did you know that this isothermal amplification method can be performed in as little as 5-10 minutes with limited resources? Learn more at https://www.neb.co Recently, reverse transcription loop-mediated isothermal amplification (RT-LAMP) has been widely deployed for the rapid and reliable detection of several RNA viruses, including SARS-CoV, MERS-CoV, and influenza. 7–9 Since RT-LAMP is an isothermal process (usually at 60 °C to 65 °C), the assay requires only a simple instrument (e.g., water bath or heating block).

2014-11-12 · FAQ: What is LAMP and RT-LAMP? LAMP provides high sensitivity (to fg or <10 copies of target) but with rapid results: reactions can be performed in as little as 5–10 minutes. Reactions can be performed with limited resources, using a water bath for incubation and detection of results by eye, or with real-time measurement and high-throughput instruments. 2020-11-01 · As observed, 40 min of the RT-LAMP process caused a color change visible to naked eye, indicating that it is possible and feasible to run RT-LAMP without the RNA extraction step. Impressively, both the N15 and O117 primer sets accurately detected all 8 positive and all 8 negative clinical samples, indicating that this developed test can be used to replace the classic RT-PCR tests for COVID-19 RT‐LAMP and sensitivity to amplify synthesized RNA of SARS‐CoV‐2. To assess the potential of RT‐LAMP in detecting RNA virus of SARS‐CoV‐2, we then tested the performance of these primers with synthesized RNA fragments of the N gene, S gene and Orf1ab gene obtained from in vitro transcription (Appendix S1). RT-LAMP technology is a one-step nucleic acid amplification method to multiply specific sequences of RNA of the coronavirus.
