AdV-mCherry was added to AdV-GFP at a ratio of 1:200 and 50 000 pp/cell of this mix was complexed with h9C12 and IVIg and indicated doses. HMDM were stimulated with these complexes for 16h and infection measured as mCherry fluorescence by flow cytometry. In virus alone the percentage of mCherry positive cells was ~ 20%, the relative infection with antibodies was normalised to virus alone as 100%.
