From: Receptor binding specificity of recent human H3N2 influenza viruses
Binding, internalization and synthesis of viral proteins in different cell lines. Surface binding of virus (4°C, 1hr), internalization (37°C,1hr), replication to amplify NP (37°C, 6 hr), and cell surface expression of HA seen by hemadsorption at 18 hr (rbc binding). Immuno staining and red cell binding was done as described in Methods.
