Figure 1From: Inhibition of cytokine gene expression and induction of chemokine genes in non-lymphatic cells infected with SARS coronavirusVirus titers. Simian Vero cells (white bars), human Caco-2 cells (grey bars), and human low-passage HEK 293 cells (black bars) were infected at a multiplicity of infection (MOI) of 5 infectious particles per cell. Virus titers in the supernatants were determined 24 h post-infection and 48 h post-infection by plaque assays.Back to article page
