Figure 3From: Lentviral-mediated RNAi to inhibit target gene expression of the porcine integrin αv subunit, the FMDV receptor, and against FMDV infection in PK-15 cellsVisualization of A. Mock (+++); B. Control (+++); and C. iαv-PK-15 (+), by IIF. Samples were incubated with primary antibody (rabbit αv integrin, 1:500) with mouse anti-rabbit IgG-FITC (1:200). Negative (-), no fluorescent cells; weakly positive (+), the signal was faint (less than 5% of cells); positive (++), 5% to 50% were readily detected; strongly positive (+++), positive staining was intense in more than 50% of cells.Back to article page
