Rapid detection of Lassa virus by reverse transcription-loop-mediated isothermal amplification

Rapid detection of Lassa virus by reverse transcription-loop-mediated isothermal amplification.

In this study, a simple one-step reverse transcription-loop-mediated isothermal amplification (RT-LAMP) assay for rapid detection of Lassa virus (LASV) was established. The two primer sets were designed to detect LASV circulating in Sierra Leone and northeastern Nigeria. The RT-LAMP assay using these primer sets was able to detect 100 copies of the in vitro transcribed artificial LASV RNA withi...

Rapid Detection of Porcine Reproductive and Respiratory Syndrome Virus by Reverse Transcription Loop-Mediated Isothermal Amplification

The fragment of the membrane protein M gene with high conservation and specificity of porcine reproductive and respiratory syndrome virus (PRRSV) was chosen to be the target region, according to which six special primers were designed successfully. Reverse transcription loop-mediated isothermal amplification (RT-LAMP) was applied to detect the PRRSV by incubation at 65° for only 45 min with the...

Rapid Detection of West Nile Virus for Loop-Mediated Isothermal Amplification Real-Time Reverse Transcription

Reverse transcription-loop-mediated isothermal amplification assay for rapid detection of hepatitis E virus.

The one-step single-tube betaine-free reverse transcription (RT)-loop-mediated isothermal amplification assay was developed for rapid diagnosis of hepatitis E virus. This assay amplified the target gene in less than 45 min (even as short as 20 min) under isothermal conditions at 63 degrees C, and the sensitivity of this assay was 100-fold greater than that of RT-PCR. This assay demonstrated a d...

Real-time reverse transcription loop-mediated isothermal amplification for rapid detection of West Nile virus.

A one-step, single tube, real-time accelerated reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for detecting the envelope gene of West Nile (WN) virus. The RT-LAMP assay is a novel method of gene amplification that amplifies nucleic acid with high specificity, efficiency, and rapidity under isothermal conditions with a set of six specially designed pri...
