Detection of the hepcidin prepropeptide and mature peptide in liver of rainbow trout.

Highlights: [•] We report an antibody against hepcidin mature peptide from rainbow trout. [•] The antibody detect the prepropeptide in rainbow trout liver. [•] The hepcidin prepropeptide was induced by iron overloading and LPS. [•] The mature peptide was identifying by mass spectrometry analyses. [•] Hepcidin could be a molecular marker with application in aquaculture and fish health. [Copyright &y& Elsevier]
