SARS CoV-2 strain 2019-nCov/Italy wild-type virus (LV), which was handled in a level 3 bio-containment facility (BSL 3), was used as positive control in order to evaluate the spike glycoprotein expression, while a ∆-envelope pseudotype, prepared with the same procedure, was used as a negative control. To verify the expression of the spike protein in the SARS-CoV-2 pseudotypes, the spike was detected by Western blot; sera from convalescent SARS-CoV-2 patients, which have been shown to have a high neutralising titre in microneutralisation with a live virus, were used as the primary antibody, and goat anti-Human IgG as the secondary antibody.	./cache/cord-349117-xfir3m5p.txt	./txt/cord-349117-xfir3m5p.txt
