Fig. 5: Total and cell surface in vitro expression assay (IVE) of selected mRNA VZV gE vaccine candidates in HEK 293T cells.

In vitro expression of mRNA VZV LNP formulated material for the three proposed vaccines candidates gE WT_Co2, ms5_Co1 and ms6_Co2 was measured by flow cytometry in HEK 293T cells and whole gE expression levels (a) or gE levels in the cell surface (b) were detected using a specific antibody against VZV gE. EC50 values (ng/well) were calculated from each curve and are shown in a table together with the (%) positive cells at 31 ng dose for both conditions tested.
