The first step in the experiment was to obtain a collection of kinome microarray data. For this, a dataset from a published kinome array experiment for investigation of the existence of species- and individual-specific kinotypes in human and pig was used [27]. There were six biological replicates for each species, i.e., twelve individuals in total. The study was run for four consecutive weeks leading to 48 arrays. Each array contained 297 peptides and 9 within-replicates for each peptide. More information about the design, construction and application of these arrays is given elsewhere [18,27].
