Multiplex qPCR Discriminates Variants of Concern to Enhance Global Surveillance of SARS-CoV-2

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Broadly accessible and inexpensive surveillance methods are needed to track Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) variants of concern (VOC) around the world. While sequencing is the gold standard to identify circulating SARS-CoV-2 variants, routine genomic surveillance is not available in many locations primarily due to a lack of resources and expertise. The Institutional Review Board from the Yale University Human Research Protection Program determined that the RT-qPCR testing and sequencing of de-identified remnant COVID-19 clinical samples conducted in this study is not research involving human patients. Multiplex-PCR products were purified by using AmpureXP beads, and quantification was carried out using the Qubit dsDNA High Sensitivity assay on the Qubit 3.0.
