From: A proteomics study of the response of North Ronaldsay sheep to copper challenge
Differential expression of cathepsin D in Cambridge and North Ronaldsay sheep at both moderate and high copper challenge. The region of the 2-D gel encompassing a protein identified as cathepsin D by MALDI-ToF MS and peptide mass fingerprinting is shown for two control animals, and two copper-challenged animals at both moderate and high copper loading. The copper level in each individual liver (mean value of dorsal and ventral lobes), determined by ICP-MS is indicated.
