Fig. 2From: Porcine Viperin protein inhibits the replication of classical swine fever virus (CSFV) in vitroDetection of CSFV replication in 3D4/21 cells and PBMCs. CSFV titers in 3D4/21 cells (a, c)  and PBMCs (b, d) at 0, 12, 24 and 48 hpi were determined by TCID50 test. Each treatment was performed in triplicate and data was shown as the mean ± S.D.Back to article page
