Ultrasensitive and fast detection of SARS-CoV-2 using RT-LAMP without pH-dependent dye.

This study investigates the performance of reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay for the colorimetric detection of SARS-CoV-2 using fluorometric dye, namely, calcein. The detection limit (LoD) with the N-ID1 primer set resulted in superior performance, corresponding to ~ 2 copies/reaction or ~ 0.1 copies/μL of the RNA sample.

Multiplex real-time RT-PCR method for the diagnosis of SARS-CoV-2 by targeting viral N, RdRP and human RP genes.

Corona Virus Disease 2019 (COVID-19) is a disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This pandemic has brought the world to a standstill and threatened human lives. Many methods are known to date to detect this virus.

Evaluation of the Idylla KRAS and NRAS mutation test in colorectal cancer tissue.

Introduction: The currently approved techniques for RAS mutations testing in colorectal cancer (CRC) tissue are labor-intensive and time consuming. The Idylla technology (IT) is a rapid and fully automated diagnostics system. The primary aim of this study is to compare the Idylla performance against that of conventional techniques (CT).

Comparative sequence analysis of Mycobacterium leprae and the new leprosy-causing Mycobacterium lepromatosis.

Mycobacterium lepromatosis is a newly discovered leprosy-causing organism. Preliminary phylogenetic analysis of its 16S rRNA gene and a few other gene segments revealed significant divergence from Mycobacterium leprae, a well-known cause of leprosy, that justifies the status of M. lepromatosis as a new species.
