Hemagglutinin subtypes are associated with LPO substrate preference supporting IAV inactivation.

<p>Susceptibilities of tested IAV strains to OSCN^- and OI^- in the cell-free system were compared according to their types of (A) hemagglutinin (H1, H3) and (B) neuraminidase (N1, N2). “SCN^-/I^- substrate preference ratios” were also calculated as described in the text for all nine IAV strains and compared among HA and NA types (upper and lower right panels). Ns, non-significant, *, p<0.05. SCN^-, thiocyanate; OSCN^-, hypothiocyanite; I^-, iodide; OI^-, hypoiodite; LPO, lactoperoxidase; GO, glucose oxidase; HA, hemagglutinin; NA, neuraminidase. The gray area highlights the only significant difference in the figure.
