New England Biolabs launches primer monitor tool for tracking SARS-CoV-2 variants

June 17, 2021
New England Biolabs, a supplier of reagents for the life sciences, launched a web-based tool for monitoring the emergence of SARS-CoV-2 variants and their potential impact on COVID-19 diagnostic tests.

The open-access Primer Monitor Tool, which is updated regularly, provides simple visualization of known variants identified in the SARS-CoV-2 genome and offers insight into where commonly used or user-defined primer-set assessment may be worthwhile.

The U.S. Food and Drug Administration (FDA) has issued a guidance advising COVID-19 diagnostic developers to evaluate the impact of emerging and future SARS-CoV-2 variants on current diagnostic tests by routinely monitoring sequence alignment of primer/probe sequences with open access SARS-CoV-2 genomes databases such as GISAID, a global science initiative and primary source that provides open-access to genomic data of influenza viruses and the novel coronavirus responsible for COVID-19.

Steven Chiu, Product Marketing Manager, DNA Amplification, at NEB, said, “The tool is pre-loaded with commonly used primer sequences from SARS-CoV-2 qPCR and LAMP assays and ARTIC sequencing workflows (currently v3). Users can monitor those predefined primer sets as well as upload their own sequences of interest, with the option to subscribe and be alerted should variation cross a specified threshold in a geographic region of interest.”
