A Molecular-Based Assay for Quantifying Influenza A and B Viruses

Abstract

Source: Otto, C. C. et al., Rapid Molecular Detection and Differentiation of Influenza Viruses A and B. J. Vis. Exp. (2017)

The video demonstrates an assay for quantifying influenza viruses A and B. This assay employs nicking endonuclease amplification with influenza-specific primers and target detection using molecular beacon probes.

Protocol

All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines. 1. Before Running the Assay NOTE: The Influenza A and B assay is approved for nasopharyngeal swab specimens and for nasopharyngeal swabs stored in viral transport media. Swabs are included in the kit and should be used for optimal performance. However, rayon, foam, flocked swabs, or polyester nasal swabs can also be us…
