RT-LAMP Introduction

This assay utilizes reverse transcription loop-mediated isothermal amplification (RT-LAMP), which amplifies SARS-CoV-2 RNA without the need for thermal cycling. This is accomplished using specialized primers that enable continuous amplification of nucleic acids at 60°C. RT-LAMP is faster than traditional RT-PCR with a colorimetric endpoint readout. Thus, detection of viral RNA can be performed by eye or with a plate reader capable of reading absorbance at 570 nm and 650 nm.

This kit uses six primer-probe sets specific to the SARS-CoV-2 gene encoding for the nucleocapsid protein. The regions selected for amplification do not share homology to nucleocapsid genes from any other coronaviruses.

Absence of viral RNA is represented by a purple color (570 nm)(see picture above). The presence of viral RNA is represented by a blue color (650 nm). An OD ratio of 650 nm / 570 more than 1.0 indicates that SARS-CoV-2 viral RNA is present.

Kit Components

This kit also has an option to include PCR tubes. 25 tests = 4 strips of 8 PCR tubes per strip. 100 tests = 13 strips of 8 PCR tubes per strip.
