COVID-19 Rapid Isothermal PCR Kit

No PCR instrument required! This PCR test kit utilizes the RT-LAMP (reverse transcription loop-mediated isothermal amplification) method for the qualitative detection of SARS-CoV-2 in purified RNA isolated from nasopharyngeal swabs. Results detected by eye or plate reader. Contact [email protected] for bulk purchases.


Assay Format

25 viral RNA copies / µL
Compatible Sample Types:
  • Extracted RNA (e.g., from a throat swab)
Method of Detection:
  • Qualitative (by eye) & Semi-Quantitative (with plate reader)

Product Specifications

25 or 100 tests (tubes)

Protein Information

Protein Name & Synonyms:
Gene encoding for the Nucleocapsid (N) protein
Number of Targets Detected:
6 regions specific to the SARS-CoV-2 N gene. The regions selected for amplification do not share homology to nucleocapsid genes from any other coronaviruses.
Plate Reader Compatibility:
Absorbance at 570 nm and 650 nm

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.
