Figure 1.

Influenza proteins as visualized by Western blot after UVA irradiation with and without INA. Two strains of influenza PR8 (H1N1 virus) and X31 (H3N2) were tested with varying treatments as specified in the figure. Western blots were subsequently probed with the antibody noted, either anti-HA2, anti-HA1 or anti-NP. The anti-NP was cross reactive to both strains, whereas anti-HA2 and anti-HA1 were strain specific. Note that the UVA samples also contain DMSO added in the same amount needed for the addition of the INA to the INA-treated samples.
