Fig 1. TaqMan assay for discriminating R.1 lineage SARS-CoV-2 by its spike variant allele.

Fig 1

We analyzed samples of R.1 lineage SARS-CoV-2 (n = 3), which harbors a spike variant with the W152L/E484K/G769V mutations and samples of SARS-CoV-2 without these three mutations (n = 5) using a TaqMan assay. An allelic discrimination plot of the results, showing the spike variants with W152L (upper), E484K (middle), and G769V (lower). The dots indicate the mutant alleles (purple), reference allele (pink), or no amplification (orange). The dotted circles indicate the mutant alleles of each variant.
