The unusually large size of HCMV, its pleomorphic envelope, the irregularly organized proteins, and the metastable nature of the gB all pose significant technical challenges to high-resolution structural characterization. (databasefootball.com)

We developed vaccines expressing the SARS -CoV-2 spike or nucleocapsid protein. (wistar.org)
