Developing multiplex ddPCR assays for SARS-CoV-2 detection based on probe mix and amplitude based multiplexing.

ABSTRACT: Introduction: With the ongoing SARS-CoV-2 pandemic, different articles have been published highlighting the superiority of droplet digital PCR (ddPCR) over the gold-standard reverse transcription PCR (RT-PCR) in SARS-CoV-2 detection. However, few studies have been reported on developing multiplex ddPCR assays for SARS-CoV-2 detection and their performance. This study shows steps on how to develop different ddPCR SAR-CoV-2 assays including higher order multiplex assays for SARS-CoV-2 detection and antiviral screening.Methods: Using multiple primer/probe sets, we developed, optimized, and analyzed the performance of simplex (1 target), duplex (2 targets), triplex probe mix (3 targets), and quadruplex (4 targets) SARS-CoV-2 ddPCR assays based on a two-color ddPCR detection syste
