Fig. 3From: Molecular identification and functional characterization of IRF4 from common carp (Cyprinus carpio. L) in immune response: a negative regulator in the IFN and NF-κB signalling pathwaysTissue-specific expression of ccIRF4 under normal physiological conditions. CcIRF4 mRNA expression in the liver, spleen, head kidney, gills, skin, foregut, hindgut, buccal epithelium, gonad, muscle and brain were determined by real-time PCR. Gene expression levels were normalized using the 40S ribosomal protein S11 mRNA, n = 3Back to article page
