Multiplex Fragment Analysis Identifies SARS-CoV-2 Variants

The rapid spread of SARS-CoV-2 Variants of Concern (VOC) necessitates systematic efforts for epidemiological surveillance. The current method for identifying variants is viral whole genome sequencing (WGS). Broad clinical adoption of sequencing is limited by costly equipment, bioinformatics support, technical expertise, and time for implementation. Here we describe a scalable, multiplex, non-sequencing-based capillary electrophoresis assay to affordably screen for SARS-CoV-2 VOC.
