چکیده
We report a one-pot, closed-vessel enzymatic assay that eliminates carryover contamination while preserving robust DNA amplification in loop-mediated isothermal amplification (LAMP), providing reliable and rapid detection of target DNA in contaminated samples.

Advanced uracil DNA glycosylase-supplemented real-time reverse transcription loop-mediated isothermal amplification (UDG-rRT-LAMP) method for universal and specific detection of Tembusu virus
Tembusu virus (TMUV) is a mosquito-borne flavivirus which threatens both poultry production and public health. In this study we developed a complete open reading frame alignment-based rRT-LAMP method for the universal detection of TUMV. To prevent false-positive results, the reaction was supplemented with uracil DNA glycosylase (UDG) to eliminate carryover contamination. The detection limit of ...
متن کاملDevelopment of uracil-DNA-glycosylase-supplemented loop-mediated isothermal amplification coupled with nanogold probe (UDG-LAMP-AuNP) for specific detection of Pseudomonas aeruginosa
Pseudomonas aeruginosa (P. aeruginosa) is an important opportunistic pathogen that causes serious infections in humans, including keratitis in contact lens wearers. Therefore, establishing a rapid, specific and sensitive method for the identification of P. aeruginosa is imperative. In the present study, the uracil-DNA-glycosylase-supplemented loop-mediated isothermal amplification combined with...
متن کاملUracil-DNA glycosylase-treated reverse transcription loop-mediated isothermal amplification for rapid detection of avian influenza virus preventing carry-over contamination
Here, we describe a uracil-DNA glycosylase (UNG)-treated reverse transcription loop-mediated isothermal amplification (uRT-LAMP) for the visual detection of all subtypes of avian influenza A virus (AIV). The uRT-LAMP assay can prevent unwanted amplification by carryover contamination of the previously amplified DNA, although the detection limit of the uRT-LAMP assay is 10-fold lower than that o...
متن کاملLoop-Mediated Isothermal Amplification (LAMP) for the Rapid Diagnosis of Herpes Simplex Virus Type 1 (HSV-1)
Background and Aims: considering difficulties in usual laboratory methods in detection of viral infections, improved DNA-based diagnostic techniques are more reliable. Loop mediated isothermal amplification method (LAMP) is a nucleic acid amplification method that amplifies DNA using six primers which has been developed to diagnose viruses as a rapid and high efficiency test. In this study, the...

Background and purpose: Fasciola hepatica and Fasciola gigantica are common liver flukes which affect both human and livestock worldwide. In this study we evaluated the loop-mediated isothermal amplification (LAMP) assay for detection and discrimination of Fasciola species. Materials and methods: Fifty adults of Fasciola worms were isolated from sheep and cattle liver form abattoirs in Mazand...
