Fig. 5From: Molecular characterization and immune functional analysis of IRF2 in common carp (Cyprinus carpio L.): different regulatory role in the IFN and NF-κB signalling pathwayExpression analysis of CcIRF2 in response to A. hydrophila challenge in vivo. Total RNA was extracted from the spleen (a), head kidney (b), foregut (c) and hindgut (d) tissues at 0 (as a control), 3, 6, 12, 24, 48 and 72 hpi for real-time PCR. The expression was normalized using that of the 40S ribosomal protein S11 (n = 3, mean ± SD, *P < 0.05)Back to article page
