Figure 5. Systemic influenza-specific IgA, but not IgG or IgM antibody levels, are higher in adult versus infant animals.

Figure 5

The amount of influenza-specific IgG, IgM, and IgA antibody in the plasma was determined at d8 and 14 postinfection. Threshold dilution was defined as the dilution at which the influenza-specific OD reading (OD from IAV coated wells – OD from uncoated wells) reached three times the assay background.
