Figure 3From: Identification of putative interactions between swine and human influenza A virus nucleoprotein and human host proteinsβ-galactosidase activity in liquid culture. Β-gal activity is a quantitative measure of the strength of interaction between bait swine or human NP and prey human host proteins identified in the Y2H screen. The β-gal activity for each interacting bait-prey pair is expressed in Miller units and represents the mean and standard error of the mean of at least eight independent samples.Back to article page
