Figure 1. Select commercially sourced cell lines infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in study of susceptibility to SARS-CoV-2 of cell lines and substrates used to diagnose and isolate influenza and other viruses. A) Vero; B) Vero 76; C) BGMK; D) CV-1; E) LLC-MK2; F) RhMK; G) A549; H) HEL; I) HeLa; J) Hela 229; K) Hep-2; L) MRC-5; M) MRHF; N) NCI-H292; O) RD; P) WI-38; Q) McCoy; R) MNA; S) MDCK; T) CRFK; U) Mv1Lu; V) H&V-Mix; W) R-Mix; X) R-Mix Too; Y) Super E-Mix. Cell lines were inoculated with the SARS-CoV-2 reporter virus encoding mNeonGreen (icSARS-CoV-2-mNG) and infected cells (green fluorescence). Microscopy images (original magnification ×10) captured 1 day postinfection, but similar results were observed through 5 days postinfection; all mNeonGreen-negative cell lines remained negative.
