Molecular characterization and expression analysis of two new C-reactive protein genes from common carp (Cyprinus carpio)

► Two new CRP genes have been characterized in carp. Seven CRP genes have been identified in zebrafish. ► Phylogenetic comparisons with sequences from other organisms have been ascertained. ► The new carp CRP genes have revealed differential expression in several organs. ► CRP levels in serum and several fish organs have been determined.
