New England Biolabs’ SARS-CoV-2 Rapid Colorimetric LAMP Assay Kit Enables Visual Detection of Novel Coronavirus In 30 Minutes

The research use only kit can be used as a simple alternative to RT-qPCR for SARS-CoV-2 analysis

IPSWICH, Mass.July 10, 2020 /PRNewswire/ — New England Biolabs® (NEB®) today announced the launch of the SARS-CoV-2 Rapid Colorimetric LAMP Assay Kit, a Research Use Only (RUO) product that can be used for the detection of novel coronavirus, SARS-CoV-2 RNA. The kit serves as a simple alternative to RT-qPCR and enables visual detection of amplification of SARS-CoV-2 nucleic acid in just 30 minutes.

The kit utilizes loop-mediated isothermal amplification (LAMP) to detect specific segments of the viral genome. This system provides a clear visual detection of amplification, based on the generation of protons and the subsequent drop in pH that occurs from the extensive DNA polymerase activity in a LAMP reaction. The decrease in pH produces a color change, with pink indicating a negative result and yellow indicating a positive result.

“RT-qPCR, the predominant nucleic acid amplification technology, requires a laboratory with sophisticated equipment, and can take hours to produce a readout,” said Steven Chiu, Product Marketing Manager, DNA Amplification at NEB. “With the SARS-CoV-2 Rapid Colorimetric LAMP Assay Kit, all you need is a simple heat source and 30 minutes to visually detect amplification of SARS CoV-2 RNA. This assay thus has the potential to be very beneficial in a low-resource or point-of-care setting.”

The kit includes WarmStart® Colorimetric LAMP 2X Master Mix with UDG (NEB #M1804) and a primer mix targeting the N and E regions of the viral genome. The WarmStart mix is an optimized formulation of Bst 2.0 WarmStart DNA Polymerase and WarmStart RTx in a special low-buffer reaction solution containing a visible pH indicator for rapid and easy detection of LAMP and RT-LAMP reactions. The inclusion of dUTP and UDG in the master mix reduces the possibility of carryover contamination between reactions.

Key features of the kit include:

  • Constant reaction temperature eliminates the need for sophisticated instrumentation, including thermocyclers
  • Assay targets N and E regions of the SARS-CoV-2 genome, enabling optimized sensitivity and specificity
  • Includes non-template control, positive control, and internal control to verify assay performance

“Many NEB products are already being used by our customers for the development and manufacture of diagnostic tools and vaccines for this novel coronavirus,” said Ted Davis, Executive Director, Business and Product Development at NEB. “This kit further solidifies NEB’s position as a supplier for virologists and molecular diagnostics developers alike, and we are proud to continue our support of COVID-19 research.”
