Method: For this purpose, RNA eluate of
N501Y positive saliva samples is further analyzed by commercially available SNIP assays for
K417N and
V1176F presence (VirSNiP SARS-CoV-2
Spike K417N and VirSNiP SARS-CoV-2
Spike V1176F, TIB MolBio, Berlin, Germany).
Method: Sample is considered positive for
K417N or
V1176F when the melting curve analysis shows a Tm of 61 C (+-2 C) or 57.9 C (+-1 C) respectively.
