qPCR analysis of IFN-stimulated genes (ISGs).

<p>Expression of ISG15 (left), MX1 (middle) and OAS1 <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0110264#pone.0110264-Shu1" target="_blank">[4]</a> was determined at (A) 24 h and (B) 72 h pi where “S” denotes swine dNSBE and “H” denotes human dNHBE cells. Fold-changes and standard deviations were calculated from Ct values run in quadruplicate relative mock and the housekeeping gene HPRT1. Time points that were significant between NSBE and NHBE cells are noted (* = p<0.05).
