SpeeDx Introduces Solution for Analysis of SARS-CoV-2 Variants

Proprietary Mutation Detection Technology Expands to Address Worrisome New Variants of COVID-19

SYDNEY, July 26, 2021– (BUSINESS WIRE) – SpeeDx Pty. Ltd., creator of innovative molecular diagnostic solutions, has just launched a new line of research reagents to support testing for circulating SARS-CoV-2 variants of concern . The rapid development of tests PlexPrime® SARS-CoV-2 Genotyping * will support research and monitoring of the range of emerging and circulating variants of SARS-CoV-2 that have been linked to increased transmissibility, decreased vaccine efficacy, or other characteristics that may require specific actions in public health matters.1

“Thanks to our unique universal substrate approach, the rapid response development team can effectively react to the complex and changing situations posed by the current COVID-19 pandemic,” said Elisa Mokany, Chief Technology Officer at SpeeDx. “We have a unique technology that excels in mutation detection applications and can be seamlessly applied to variants reported in SARS-CoV-2 sequence databases.”

PlexPrime® SARS-CoV-2 Alpha / Beta / Gamma + *, the first product in the portfolio, is a single-well multiplex designed to detect the N501Y, S982A and E484K mutations in the gene encoding the SARS-CoV spike protein. -2 found in the worrying variants B.1.1.7 (Alpha), B.1.351 (Beta) and P.1 (Gamma). A second multiplex will be released shortly for mutations related to the Delta variant of concern, and other mutations are currently being evaluated. The tests, which are compatible with standard qPCR instruments, can reduce the manual process of preparing positive samples for sequence analysis by identifying samples of interest, targeting downstream activities, and ultimately reduces response time and laboratory work.
