"Whole body distribution of spike S1 protein in a mouse model
To identify all potential tissues that are targeted by SARS-CoV-2, we mapped the distribution of fluorescently labeled spike S1 protein in intact transparent mice. While not a direct measurement of viral tropism, recent studies demonstrated the utility of the recombinant spike protein as a proxy to study SARS-CoV-2 targeting and pathology in mice32,27."
