- title: Detection of genetically modified organisms (GMOs) using isothermal amplification of target DNA sequences
- date: 2009-02-02
- words: 2901
- flesch: 50
- summary: This work shows that GMO detection can be carried out using LAMP for routine screening as well as for specific events detection. We have tested the upper limits of DNA that LAMP reactions can tolerate and found that up to 200 ng DNA in a 20 μl reaction, positive detection is reproducible.

The advantages of using OPIPH RT-LAMP systems compared with conventional NV detection kits are: (1) sensitivity is higher in some NV genotypes (GI.3 and GII.3); (2) specific GI genotypes (GI.3, 11, and 12) that cannot be detected by a conventional GI kit can be detected by the GI primer set developed in this study; and (3) additional treatment, that is, heating at 958C for 5 min and being kept on ice for 5 min, is not required in the OPIPH system.

- summary: LAMP amplifi cation can also be accomplished with the two outer (F3 and B3) and two internal primers (FIP and BIP) but by using the two loop primers (FLP and BLP), the amplifi cation is accelerated and thereby shortens amplifi cation time by one third to one half ( (Notomi et al 2000) . Designing of a highly sensitive and specifi c primer set is crucial for performing LAMP amplifi cation.

- summary: In the present study, the detection of CHIK virus RNA in 48.6% of samples by RT-PCR and in 55.4% of samples by RT-LAMP, as well as the detection of IgM antibodies in 21.5% of samples, confi med that the causative agent of this epidemic was CHIK virus. As is the case for most alphaviruses, detection of CHIK virus depends on isolation of the virus in blood specimens obtained from viremic patients or in infected tissue specimens obtained from blood-feeding arthropods, which are time-consuming.

- summary: Therefore, it appeared that the N-A primer set used for the RT-LAMP assay performed equally well with either IVT RNA or RNA samples isolated from the pharyngeal swab specimens. For samples with a CT ≤ 30 as measured by RT-qPCR with E-Sarbeco primers, we found overall satisfactory sensitivity and specificity values for SARS-CoV-2 RNA detection by the RT-LAMP assay using RNA samples isolated from pharyngeal swab specimens ( Fig. 3 and Table 1 ).

- summary: The RT-LAMP assay described is unique in that it offers the most thorough clinical validation to date meeting regulatory standards which include precision studies on several instruments, reproducibility studies over 20 days, a robust clinical validation sample set, and a limit of detection equal or superior to other LAMP studies (50 copies per reaction). LAMP primer sets were designed targeting unique regions of the Spike (S) protein gene and RNA-dependent RNA Polymerase gene (RdRP) were ultimately used (Table 1) .

- summary: This test was additionally verified using RNA samples purified from respiratory swabs collected from COVID-19 patients in Wuhan, China with equivalent performance to a commercial RT-qPCR test while requiring only heating and visual inspection. This study describes testing and validation of 5 sets LAMP primers targeting two fragments of the SARS-CoV-2 genome using short (~300bp) RNA fragments made with in vitro transcription and RNA samples from patients.

- summary: However, this extreme sensitivity is also a double-edged sword: carry-over contamination was common in LAMP reactions, which usually cause false positive results (Hsieh et al., 2014; Ma et al., 2017) . Primers were designed using LAMP primer designing software, PrimerExplorer (http:// primerexplorer.jp/e/; Tomita et al., 2008) .

- summary: Next, the reaction was diluted with 80 μl of HybriDetect Buffer (Milenia), mixed, and then a HybriDetect dipstick (Milenia) was placed in the reaction tube and incubated at RT. Transferring such assays to automated microfluidic formats [11] can become an important tool to support disease control strategies.
