Reduction of IAV infection by RpSP-D.

<p>Using the infection reduction assay, the neutralization of IAV by various doses of RpSP-D was assessed. The reduction of infectivity was expressed as the relative number of cells that became infected according to the formula: % reduction = 1-(% infected cells in presence of RpSP-D/% infected cells without RpSP-D)*100%. The viruses were grouped by subtype and origin: swine H3N2 (A), human H3N2 (B), avian H3N2 (C), 2009 pandemic H1N1 (D), avian-like swine H1N1 (E), classical swine (F), human H1N1 (G), avian H1N1 (H) and H5N1 (I). The average of triplicate wells is shown.
