Restriction fragments for differentiating SARS‐CoV‐2 with SARS‐CoV on agarose gel electrophoresis. (A) Lanes 1 and 3: amplicons of E gene of SARS‐CoV and SARS‐CoV‐2 were digested with AluI; lane 2: DNA ladder 100 bp. (B) Lanes 1 and 3: amplicons of RdRp gene of SARS‐CoV and SARS‐CoV‐2 were digested with Tsp45I; lane 2: DNA ladder 100 bp. (C) Lanes 1 and 3: amplicons of RdRp gene of SARS‐CoV and SARS‐CoV‐2 were digested with EcoRI; lane 2: DNA ladder 100 bp. SARS‐CoV, severe acute respiratory syndrome coronavirus
