Stabilizing effect of viscosity enhancer on the functional HA activity of dried vaccine coatings on plasma-cleaned Ti plates with formulations containing both Lutrol and CMC. The effects of viscosity enhancer (CMC) on the activity of the influenza viruses (1 μg viral protein) were investigated by measuring HA titers in different vaccine coating formulations after one day drying at ambient conditions. CMC concentration was varied at fixed trehalose/Lutrol concentration (T15L0.5C0.25, T15L0.5C0.5, T15L0.5C1) and Lutrol concentration was varied at fixed trehalose/CMC concentration (T15L0.5C0.25, T15L1C0.25, T15L2C0.25).
