(A) Detection of SARS-CoV-2 variants with the original probe, including patient samples confirmed as SARS-CoV-2 Alpha variant as positive control and SARS-CoV-2 negative patient samples and a water as negative controls. (B) Samples were tested as multiplex RT-qPCRs; E-Sarbeco in parallel with the ΔH69/V70 RT-qPCR. Error bars in (A-B) indicate SEM for three biological replicates.
