Maps of expression vectors used in this study
(A) The map of a vector expressing SARS-CoV-2 B.1.1 S protein harboring a D614G mutation, pC-SARS-2 S D614G. The SARS-CoV-2 Delta and Omicron BA.1 S protein expression vector maps are the same except for the size of each S gene. The B.1.1, Delta, and Omicron BA.1 S genes are 3822 bp, 3816 bp, and 3813 bp, respectively.
(B) The pC-ACE2 vector map.
(C) The pC-TMPRSS2 vector map.
(D) The pDSP1–7 vector map.
(E) The pDSP8–11 vector map. All vector maps were created by SnapGene.
