Development of Multiplex Real-Time RT-qPCR Assays for the Detection of SARS-CoV-2, Influenza A/B, and MERS-CoV

Overview

This study presents the development of two probe-based one-step RT-qPCR kits designed for the simultaneous detection of common respiratory viruses, including SARS-CoV-2, MERS, and various strains of Influenza. These kits enhance the diagnostic capabilities of specialized laboratories through a cost-effective and time-efficient approach.
